Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478720, here are decompositions:

  • 71 + 33478649 = 33478720
  • 113 + 33478607 = 33478720
  • 137 + 33478583 = 33478720
  • 251 + 33478469 = 33478720
  • 281 + 33478439 = 33478720
  • 383 + 33478337 = 33478720
  • 389 + 33478331 = 33478720
  • 521 + 33478199 = 33478720

Showing the first eight; more decompositions exist.
