Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691542, here are decompositions:

  • 61 + 8691481 = 8691542
  • 73 + 8691469 = 8691542
  • 109 + 8691433 = 8691542
  • 151 + 8691391 = 8691542
  • 229 + 8691313 = 8691542
  • 313 + 8691229 = 8691542
  • 331 + 8691211 = 8691542
  • 499 + 8691043 = 8691542

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 8,691,542 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 8691542 first appears in π at position 203,709 of the decimal expansion (the 203,709ordinal-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.
