Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30996, here are decompositions:

  • 13 + 30983 = 30996
  • 19 + 30977 = 30996
  • 47 + 30949 = 30996
  • 59 + 30937 = 30996
  • 103 + 30893 = 30996
  • 127 + 30869 = 30996
  • 137 + 30859 = 30996
  • 157 + 30839 = 30996

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30996 first appears in π at position 745 of the decimal expansion (the 745ordinal-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.
