Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61186, here are decompositions:

  • 17 + 61169 = 61186
  • 179 + 61007 = 61186
  • 233 + 60953 = 61186
  • 263 + 60923 = 61186
  • 269 + 60917 = 61186
  • 317 + 60869 = 61186
  • 449 + 60737 = 61186
  • 467 + 60719 = 61186

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61186 first appears in π at position 1,895 of the decimal expansion (the 1,895ordinal-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.
