Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157574, here are decompositions:

  • 3 + 157571 = 157574
  • 13 + 157561 = 157574
  • 31 + 157543 = 157574
  • 61 + 157513 = 157574
  • 97 + 157477 = 157574
  • 163 + 157411 = 157574
  • 181 + 157393 = 157574
  • 211 + 157363 = 157574

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 157,574 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 157574 first appears in π at position 46,088 of the decimal expansion (the 46,088ordinal-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.
