Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151526, here are decompositions:

  • 3 + 151523 = 151526
  • 19 + 151507 = 151526
  • 43 + 151483 = 151526
  • 97 + 151429 = 151526
  • 103 + 151423 = 151526
  • 223 + 151303 = 151526
  • 283 + 151243 = 151526
  • 313 + 151213 = 151526

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 151,526 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 151526 first appears in π at position 999,895 of the decimal expansion (the 999,895ordinal-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.
