Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190442, here are decompositions:

  • 73 + 190369 = 190442
  • 103 + 190339 = 190442
  • 181 + 190261 = 190442
  • 193 + 190249 = 190442
  • 199 + 190243 = 190442
  • 283 + 190159 = 190442
  • 313 + 190129 = 190442
  • 349 + 190093 = 190442

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 190,442 and was likely granted around 1875.

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

Position in π

The digit sequence 190442 first appears in π at position 112,366 of the decimal expansion (the 112,366ordinal-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.
