Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7490, here are decompositions:

  • 3 + 7487 = 7490
  • 13 + 7477 = 7490
  • 31 + 7459 = 7490
  • 73 + 7417 = 7490
  • 79 + 7411 = 7490
  • 97 + 7393 = 7490
  • 139 + 7351 = 7490
  • 157 + 7333 = 7490

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7490 first appears in π at position 24,833 of the decimal expansion (the 24,833ordinal-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.
