Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4992, here are decompositions:

  • 5 + 4987 = 4992
  • 19 + 4973 = 4992
  • 23 + 4969 = 4992
  • 41 + 4951 = 4992
  • 59 + 4933 = 4992
  • 61 + 4931 = 4992
  • 73 + 4919 = 4992
  • 83 + 4909 = 4992

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 4992 first appears in π at position 8,744 of the decimal expansion (the 8,744ordinal-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.
