Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61488, here are decompositions:

  • 5 + 61483 = 61488
  • 17 + 61471 = 61488
  • 19 + 61469 = 61488
  • 47 + 61441 = 61488
  • 71 + 61417 = 61488
  • 79 + 61409 = 61488
  • 107 + 61381 = 61488
  • 109 + 61379 = 61488

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61488 first appears in π at position 256,686 of the decimal expansion (the 256,686ordinal-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.
