Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487090, here are decompositions:

  • 11 + 487079 = 487090
  • 17 + 487073 = 487090
  • 41 + 487049 = 487090
  • 83 + 487007 = 487090
  • 113 + 486977 = 487090
  • 167 + 486923 = 487090
  • 251 + 486839 = 487090
  • 257 + 486833 = 487090

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 487,090 and was likely granted around 1892.

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

Position in π

The digit sequence 487090 first appears in π at position 23,679 of the decimal expansion (the 23,679ordinal-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.
