Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7506, here are decompositions:

  • 7 + 7499 = 7506
  • 17 + 7489 = 7506
  • 19 + 7487 = 7506
  • 29 + 7477 = 7506
  • 47 + 7459 = 7506
  • 73 + 7433 = 7506
  • 89 + 7417 = 7506
  • 113 + 7393 = 7506

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7506 first appears in π at position 26,954 of the decimal expansion (the 26,954ordinal-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.
