Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24528, here are decompositions:

  • 11 + 24517 = 24528
  • 19 + 24509 = 24528
  • 29 + 24499 = 24528
  • 47 + 24481 = 24528
  • 59 + 24469 = 24528
  • 89 + 24439 = 24528
  • 107 + 24421 = 24528
  • 109 + 24419 = 24528

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 24528 first appears in π at position 51,716 of the decimal expansion (the 51,716ordinal-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.
