Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939442, here are decompositions:

  • 3 + 939439 = 939442
  • 11 + 939431 = 939442
  • 29 + 939413 = 939442
  • 83 + 939359 = 939442
  • 149 + 939293 = 939442
  • 239 + 939203 = 939442
  • 263 + 939179 = 939442
  • 353 + 939089 = 939442

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 939,442 and was likely granted around 1909.

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

Position in π

The digit sequence 939442 first appears in π at position 803,977 of the decimal expansion (the 803,977ordinal-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.
