Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669438, here are decompositions:

  • 97 + 8669341 = 8669438
  • 109 + 8669329 = 8669438
  • 199 + 8669239 = 8669438
  • 331 + 8669107 = 8669438
  • 367 + 8669071 = 8669438
  • 397 + 8669041 = 8669438
  • 487 + 8668951 = 8669438
  • 541 + 8668897 = 8669438

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,669,438 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8669438 first appears in π at position 706,107 of the decimal expansion (the 706,107ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
