Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538488, here are decompositions:

  • 7 + 538481 = 538488
  • 17 + 538471 = 538488
  • 31 + 538457 = 538488
  • 89 + 538399 = 538488
  • 131 + 538357 = 538488
  • 157 + 538331 = 538488
  • 179 + 538309 = 538488
  • 191 + 538297 = 538488

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 538,488 and was likely granted around 1894.

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

Position in π

The digit sequence 538488 first appears in π at position 151,047 of the decimal expansion (the 151,047ordinal-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.
