Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2030, here are decompositions:

  • 3 + 2027 = 2030
  • 13 + 2017 = 2030
  • 19 + 2011 = 2030
  • 31 + 1999 = 2030
  • 37 + 1993 = 2030
  • 43 + 1987 = 2030
  • 79 + 1951 = 2030
  • 97 + 1933 = 2030

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2030 first appears in π at position 25,896 of the decimal expansion (the 25,896ordinal-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.
