Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7488, here are decompositions:

  • 7 + 7481 = 7488
  • 11 + 7477 = 7488
  • 29 + 7459 = 7488
  • 31 + 7457 = 7488
  • 37 + 7451 = 7488
  • 71 + 7417 = 7488
  • 137 + 7351 = 7488
  • 139 + 7349 = 7488

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7488 first appears in π at position 320 of the decimal expansion (the 320ordinal-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.
