Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61894, here are decompositions:

  • 23 + 61871 = 61894
  • 113 + 61781 = 61894
  • 137 + 61757 = 61894
  • 191 + 61703 = 61894
  • 227 + 61667 = 61894
  • 251 + 61643 = 61894
  • 257 + 61637 = 61894
  • 263 + 61631 = 61894

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61894 first appears in π at position 47,549 of the decimal expansion (the 47,549ordinal-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.
