Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124528, here are decompositions:

  • 101 + 124427 = 124528
  • 179 + 124349 = 124528
  • 191 + 124337 = 124528
  • 227 + 124301 = 124528
  • 251 + 124277 = 124528
  • 281 + 124247 = 124528
  • 347 + 124181 = 124528
  • 389 + 124139 = 124528

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 124,528 and was likely granted around 1871.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 124528 first appears in π at position 51,715 of the decimal expansion (the 51,715ordinal-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.
