Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142574, here are decompositions:

  • 7 + 142567 = 142574
  • 31 + 142543 = 142574
  • 37 + 142537 = 142574
  • 73 + 142501 = 142574
  • 193 + 142381 = 142574
  • 277 + 142297 = 142574
  • 337 + 142237 = 142574
  • 463 + 142111 = 142574

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 142,574 and was likely granted around 1872.

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

Position in π

The digit sequence 142574 first appears in π at position 67,863 of the decimal expansion (the 67,863ordinal-suffix:rd 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.
