Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543754, here are decompositions:

  • 3 + 31543751 = 31543754
  • 31 + 31543723 = 31543754
  • 43 + 31543711 = 31543754
  • 211 + 31543543 = 31543754
  • 223 + 31543531 = 31543754
  • 523 + 31543231 = 31543754
  • 547 + 31543207 = 31543754
  • 787 + 31542967 = 31543754

Showing the first eight; more decompositions exist.
