Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77470, here are decompositions:

  • 23 + 77447 = 77470
  • 53 + 77417 = 77470
  • 101 + 77369 = 77470
  • 131 + 77339 = 77470
  • 179 + 77291 = 77470
  • 191 + 77279 = 77470
  • 227 + 77243 = 77470
  • 233 + 77237 = 77470

Showing the first eight; more decompositions exist.
