Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160442, here are decompositions:

  • 19 + 160423 = 160442
  • 199 + 160243 = 160442
  • 211 + 160231 = 160442
  • 241 + 160201 = 160442
  • 283 + 160159 = 160442
  • 349 + 160093 = 160442
  • 409 + 160033 = 160442
  • 433 + 160009 = 160442

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 160,442 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 160442 first appears in π at position 511,432 of the decimal expansion (the 511,432ordinal-suffix:nd 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.
