Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469978, here are decompositions:

  • 59 + 469919 = 469978
  • 71 + 469907 = 469978
  • 101 + 469877 = 469978
  • 137 + 469841 = 469978
  • 167 + 469811 = 469978
  • 191 + 469787 = 469978
  • 347 + 469631 = 469978
  • 389 + 469589 = 469978

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 469,978 and was likely granted around 1891.

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

Position in π

The digit sequence 469978 first appears in π at position 627,090 of the decimal expansion (the 627,090ordinal-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.
