Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2084, here are decompositions:

  • 3 + 2081 = 2084
  • 31 + 2053 = 2084
  • 67 + 2017 = 2084
  • 73 + 2011 = 2084
  • 97 + 1987 = 2084
  • 151 + 1933 = 2084
  • 211 + 1873 = 2084
  • 223 + 1861 = 2084

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2084 first appears in π at position 3,714 of the decimal expansion (the 3,714ordinal-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.
