Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149520, here are decompositions:

  • 17 + 149503 = 149520
  • 23 + 149497 = 149520
  • 29 + 149491 = 149520
  • 31 + 149489 = 149520
  • 61 + 149459 = 149520
  • 79 + 149441 = 149520
  • 97 + 149423 = 149520
  • 101 + 149419 = 149520

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 149,520 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 149520 first appears in π at position 616,108 of the decimal expansion (the 616,108ordinal-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.
