Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1992, here are decompositions:

  • 5 + 1987 = 1992
  • 13 + 1979 = 1992
  • 19 + 1973 = 1992
  • 41 + 1951 = 1992
  • 43 + 1949 = 1992
  • 59 + 1933 = 1992
  • 61 + 1931 = 1992
  • 79 + 1913 = 1992

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1992 first appears in π at position 1,384 of the decimal expansion (the 1,384ordinal-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.
