Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490618, here are decompositions:

  • 41 + 490577 = 490618
  • 47 + 490571 = 490618
  • 59 + 490559 = 490618
  • 137 + 490481 = 490618
  • 197 + 490421 = 490618
  • 251 + 490367 = 490618
  • 347 + 490271 = 490618
  • 449 + 490169 = 490618

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 490,618 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 490618 first appears in π at position 423,423 of the decimal expansion (the 423,423ordinal-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.
