Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469890, here are decompositions:

  • 11 + 469879 = 469890
  • 13 + 469877 = 469890
  • 41 + 469849 = 469890
  • 67 + 469823 = 469890
  • 79 + 469811 = 469890
  • 89 + 469801 = 469890
  • 97 + 469793 = 469890
  • 103 + 469787 = 469890

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 469,890 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 469890 first appears in π at position 70,053 of the decimal expansion (the 70,053ordinal-suffix:rd 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.
