Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142892, here are decompositions:

  • 19 + 142873 = 142892
  • 103 + 142789 = 142892
  • 181 + 142711 = 142892
  • 193 + 142699 = 142892
  • 283 + 142609 = 142892
  • 349 + 142543 = 142892
  • 439 + 142453 = 142892
  • 523 + 142369 = 142892

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 142,892 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 142892 first appears in π at position 167,611 of the decimal expansion (the 167,611ordinal-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.
