Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156782, here are decompositions:

  • 79 + 156703 = 156782
  • 103 + 156679 = 156782
  • 151 + 156631 = 156782
  • 163 + 156619 = 156782
  • 181 + 156601 = 156782
  • 193 + 156589 = 156782
  • 271 + 156511 = 156782
  • 421 + 156361 = 156782

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 156,782 and was likely granted around 1873.

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

Position in π

The digit sequence 156782 first appears in π at position 299,892 of the decimal expansion (the 299,892ordinal-suffix:nd 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.
