Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561160, here are decompositions:

  • 71 + 33561089 = 33561160
  • 107 + 33561053 = 33561160
  • 137 + 33561023 = 33561160
  • 317 + 33560843 = 33561160
  • 419 + 33560741 = 33561160
  • 431 + 33560729 = 33561160
  • 443 + 33560717 = 33561160
  • 449 + 33560711 = 33561160

Showing the first eight; more decompositions exist.
