Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549490, here are decompositions:

  • 41 + 549449 = 549490
  • 47 + 549443 = 549490
  • 59 + 549431 = 549490
  • 167 + 549323 = 549490
  • 233 + 549257 = 549490
  • 269 + 549221 = 549490
  • 401 + 549089 = 549490
  • 419 + 549071 = 549490

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 549,490 and was likely granted around 1895.

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

Position in π

The digit sequence 549490 first appears in π at position 685,634 of the decimal expansion (the 685,634ordinal-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.
