Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1976, here are decompositions:

  • 3 + 1973 = 1976
  • 43 + 1933 = 1976
  • 97 + 1879 = 1976
  • 103 + 1873 = 1976
  • 109 + 1867 = 1976
  • 193 + 1783 = 1976
  • 199 + 1777 = 1976
  • 223 + 1753 = 1976

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1976 first appears in π at position 3,839 of the decimal expansion (the 3,839ordinal-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.
