Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30916, here are decompositions:

  • 5 + 30911 = 30916
  • 23 + 30893 = 30916
  • 47 + 30869 = 30916
  • 107 + 30809 = 30916
  • 113 + 30803 = 30916
  • 227 + 30689 = 30916
  • 239 + 30677 = 30916
  • 359 + 30557 = 30916

Showing the first eight; more decompositions exist.
