Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542622, here are decompositions:

  • 113 + 31542509 = 31542622
  • 263 + 31542359 = 31542622
  • 281 + 31542341 = 31542622
  • 389 + 31542233 = 31542622
  • 509 + 31542113 = 31542622
  • 599 + 31542023 = 31542622
  • 641 + 31541981 = 31542622
  • 719 + 31541903 = 31542622

Showing the first eight; more decompositions exist.
