Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49920, here are decompositions:

  • 29 + 49891 = 49920
  • 43 + 49877 = 49920
  • 67 + 49853 = 49920
  • 89 + 49831 = 49920
  • 97 + 49823 = 49920
  • 109 + 49811 = 49920
  • 113 + 49807 = 49920
  • 131 + 49789 = 49920

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 49920 first appears in π at position 56,841 of the decimal expansion (the 56,841ordinal-suffix:st 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.
