Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622432, here are decompositions:

  • 3 + 31622429 = 31622432
  • 43 + 31622389 = 31622432
  • 139 + 31622293 = 31622432
  • 151 + 31622281 = 31622432
  • 313 + 31622119 = 31622432
  • 601 + 31621831 = 31622432
  • 739 + 31621693 = 31622432
  • 811 + 31621621 = 31622432

Showing the first eight; more decompositions exist.
