Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624434, here are decompositions:

  • 5 + 31624429 = 31624434
  • 11 + 31624423 = 31624434
  • 47 + 31624387 = 31624434
  • 67 + 31624367 = 31624434
  • 71 + 31624363 = 31624434
  • 97 + 31624337 = 31624434
  • 103 + 31624331 = 31624434
  • 113 + 31624321 = 31624434

Showing the first eight; more decompositions exist.
