Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49840, here are decompositions:

  • 17 + 49823 = 49840
  • 29 + 49811 = 49840
  • 53 + 49787 = 49840
  • 83 + 49757 = 49840
  • 101 + 49739 = 49840
  • 113 + 49727 = 49840
  • 173 + 49667 = 49840
  • 227 + 49613 = 49840

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 49840 first appears in π at position 56,993 of the decimal expansion (the 56,993ordinal-suffix:rd 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.
