Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142372, here are decompositions:

  • 3 + 142369 = 142372
  • 53 + 142319 = 142372
  • 101 + 142271 = 142372
  • 149 + 142223 = 142372
  • 179 + 142193 = 142372
  • 311 + 142061 = 142372
  • 353 + 142019 = 142372
  • 401 + 141971 = 142372

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 142,372 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 142372 first appears in π at position 53,066 of the decimal expansion (the 53,066ordinal-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.
