Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162786, here are decompositions:

  • 7 + 162779 = 162786
  • 37 + 162749 = 162786
  • 47 + 162739 = 162786
  • 59 + 162727 = 162786
  • 73 + 162713 = 162786
  • 83 + 162703 = 162786
  • 103 + 162683 = 162786
  • 109 + 162677 = 162786

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 162,786 and was likely granted around 1874.

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

Position in π

The digit sequence 162786 first appears in π at position 790,295 of the decimal expansion (the 790,295ordinal-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.
