Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543538, here are decompositions:

  • 7 + 31543531 = 31543538
  • 109 + 31543429 = 31543538
  • 307 + 31543231 = 31543538
  • 331 + 31543207 = 31543538
  • 547 + 31542991 = 31543538
  • 571 + 31542967 = 31543538
  • 601 + 31542937 = 31543538
  • 661 + 31542877 = 31543538

Showing the first eight; more decompositions exist.
