Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30078, here are decompositions:

  • 7 + 30071 = 30078
  • 19 + 30059 = 30078
  • 31 + 30047 = 30078
  • 67 + 30011 = 30078
  • 89 + 29989 = 30078
  • 131 + 29947 = 30078
  • 151 + 29927 = 30078
  • 157 + 29921 = 30078

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30078 first appears in π at position 44,502 of the decimal expansion (the 44,502ordinal-suffix:nd 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.
