Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487330, here are decompositions:

  • 17 + 487313 = 487330
  • 23 + 487307 = 487330
  • 47 + 487283 = 487330
  • 83 + 487247 = 487330
  • 197 + 487133 = 487330
  • 251 + 487079 = 487330
  • 257 + 487073 = 487330
  • 281 + 487049 = 487330

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 487,330 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 487330 first appears in π at position 861,762 of the decimal expansion (the 861,762ordinal-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.
