Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538390, here are decompositions:

  • 23 + 538367 = 538390
  • 59 + 538331 = 538390
  • 89 + 538301 = 538390
  • 107 + 538283 = 538390
  • 131 + 538259 = 538390
  • 191 + 538199 = 538390
  • 227 + 538163 = 538390
  • 233 + 538157 = 538390

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 538,390 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 538390 first appears in π at position 108,836 of the decimal expansion (the 108,836ordinal-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.
