Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617534, here are decompositions:

  • 5 + 31617529 = 31617534
  • 31 + 31617503 = 31617534
  • 37 + 31617497 = 31617534
  • 41 + 31617493 = 31617534
  • 73 + 31617461 = 31617534
  • 103 + 31617431 = 31617534
  • 127 + 31617407 = 31617534
  • 131 + 31617403 = 31617534

Showing the first eight; more decompositions exist.
