Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155732, here are decompositions:

  • 13 + 155719 = 155732
  • 43 + 155689 = 155732
  • 61 + 155671 = 155732
  • 79 + 155653 = 155732
  • 139 + 155593 = 155732
  • 151 + 155581 = 155732
  • 163 + 155569 = 155732
  • 193 + 155539 = 155732

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 155,732 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 155732 first appears in π at position 51,463 of the decimal expansion (the 51,463ordinal-suffix:rd 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.
