Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75490, here are decompositions:

  • 11 + 75479 = 75490
  • 53 + 75437 = 75490
  • 59 + 75431 = 75490
  • 83 + 75407 = 75490
  • 89 + 75401 = 75490
  • 101 + 75389 = 75490
  • 113 + 75377 = 75490
  • 137 + 75353 = 75490

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 75490 first appears in π at position 106,693 of the decimal expansion (the 106,693ordinal-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.
