Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542942, here are decompositions:

  • 5 + 31542937 = 31542942
  • 31 + 31542911 = 31542942
  • 61 + 31542881 = 31542942
  • 113 + 31542829 = 31542942
  • 131 + 31542811 = 31542942
  • 239 + 31542703 = 31542942
  • 283 + 31542659 = 31542942
  • 311 + 31542631 = 31542942

Showing the first eight; more decompositions exist.
