Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51844, here are decompositions:

  • 5 + 51839 = 51844
  • 17 + 51827 = 51844
  • 41 + 51803 = 51844
  • 47 + 51797 = 51844
  • 131 + 51713 = 51844
  • 197 + 51647 = 51844
  • 251 + 51593 = 51844
  • 263 + 51581 = 51844

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51844 first appears in π at position 353,799 of the decimal expansion (the 353,799ordinal-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.
