Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624626, here are decompositions:

  • 13 + 31624613 = 31624626
  • 29 + 31624597 = 31624626
  • 67 + 31624559 = 31624626
  • 79 + 31624547 = 31624626
  • 149 + 31624477 = 31624626
  • 197 + 31624429 = 31624626
  • 239 + 31624387 = 31624626
  • 263 + 31624363 = 31624626

Showing the first eight; more decompositions exist.
