Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4988, here are decompositions:

  • 19 + 4969 = 4988
  • 31 + 4957 = 4988
  • 37 + 4951 = 4988
  • 79 + 4909 = 4988
  • 127 + 4861 = 4988
  • 157 + 4831 = 4988
  • 199 + 4789 = 4988
  • 229 + 4759 = 4988

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 4988 first appears in π at position 1,776 of the decimal expansion (the 1,776ordinal-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.
