Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723284, here are decompositions:

  • 41 + 8723243 = 8723284
  • 71 + 8723213 = 8723284
  • 293 + 8722991 = 8723284
  • 443 + 8722841 = 8723284
  • 641 + 8722643 = 8723284
  • 653 + 8722631 = 8723284
  • 677 + 8722607 = 8723284
  • 743 + 8722541 = 8723284

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 8,723,284 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 8723284 first appears in π at position 461,055 of the decimal expansion (the 461,055ordinal-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.
