Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155582, here are decompositions:

  • 3 + 155579 = 155582
  • 13 + 155569 = 155582
  • 43 + 155539 = 155582
  • 61 + 155521 = 155582
  • 73 + 155509 = 155582
  • 109 + 155473 = 155582
  • 139 + 155443 = 155582
  • 199 + 155383 = 155582

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 155,582 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 155582 first appears in π at position 141,288 of the decimal expansion (the 141,288ordinal-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.
