Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7528, here are decompositions:

  • 5 + 7523 = 7528
  • 11 + 7517 = 7528
  • 29 + 7499 = 7528
  • 41 + 7487 = 7528
  • 47 + 7481 = 7528
  • 71 + 7457 = 7528
  • 179 + 7349 = 7528
  • 197 + 7331 = 7528

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7528 first appears in π at position 865 of the decimal expansion (the 865ordinal-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.
