Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517880, here are decompositions:

  • 7 + 33517873 = 33517880
  • 31 + 33517849 = 33517880
  • 127 + 33517753 = 33517880
  • 139 + 33517741 = 33517880
  • 199 + 33517681 = 33517880
  • 229 + 33517651 = 33517880
  • 241 + 33517639 = 33517880
  • 307 + 33517573 = 33517880

Showing the first eight; more decompositions exist.
