Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61888, here are decompositions:

  • 17 + 61871 = 61888
  • 107 + 61781 = 61888
  • 131 + 61757 = 61888
  • 137 + 61751 = 61888
  • 251 + 61637 = 61888
  • 257 + 61631 = 61888
  • 401 + 61487 = 61888
  • 419 + 61469 = 61888

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61888 first appears in π at position 37,225 of the decimal expansion (the 37,225ordinal-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.
