Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2098, here are decompositions:

  • 11 + 2087 = 2098
  • 17 + 2081 = 2098
  • 29 + 2069 = 2098
  • 59 + 2039 = 2098
  • 71 + 2027 = 2098
  • 101 + 1997 = 2098
  • 149 + 1949 = 2098
  • 167 + 1931 = 2098

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2098 first appears in π at position 5,825 of the decimal expansion (the 5,825ordinal-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.
