Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2022, here are decompositions:

  • 5 + 2017 = 2022
  • 11 + 2011 = 2022
  • 19 + 2003 = 2022
  • 23 + 1999 = 2022
  • 29 + 1993 = 2022
  • 43 + 1979 = 2022
  • 71 + 1951 = 2022
  • 73 + 1949 = 2022

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2022 first appears in π at position 17,952 of the decimal expansion (the 17,952ordinal-suffix:nd 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.
