Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504832, here are decompositions:

  • 13 + 31504819 = 31504832
  • 31 + 31504801 = 31504832
  • 181 + 31504651 = 31504832
  • 241 + 31504591 = 31504832
  • 379 + 31504453 = 31504832
  • 613 + 31504219 = 31504832
  • 631 + 31504201 = 31504832
  • 643 + 31504189 = 31504832

Showing the first eight; more decompositions exist.
