Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542124, here are decompositions:

  • 11 + 31542113 = 31542124
  • 41 + 31542083 = 31542124
  • 101 + 31542023 = 31542124
  • 113 + 31542011 = 31542124
  • 191 + 31541933 = 31542124
  • 233 + 31541891 = 31542124
  • 431 + 31541693 = 31542124
  • 491 + 31541633 = 31542124

Showing the first eight; more decompositions exist.
