Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478586, here are decompositions:

  • 7 + 478579 = 478586
  • 13 + 478573 = 478586
  • 103 + 478483 = 478586
  • 127 + 478459 = 478586
  • 313 + 478273 = 478586
  • 373 + 478213 = 478586
  • 379 + 478207 = 478586
  • 397 + 478189 = 478586

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 478,586 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 478586 first appears in π at position 245,485 of the decimal expansion (the 245,485ordinal-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.
