Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155502, here are decompositions:

  • 29 + 155473 = 155502
  • 41 + 155461 = 155502
  • 59 + 155443 = 155502
  • 79 + 155423 = 155502
  • 89 + 155413 = 155502
  • 103 + 155399 = 155502
  • 131 + 155371 = 155502
  • 199 + 155303 = 155502

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 155,502 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 155502 first appears in π at position 332,639 of the decimal expansion (the 332,639ordinal-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.
