Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620284, here are decompositions:

  • 7 + 8620277 = 8620284
  • 17 + 8620267 = 8620284
  • 53 + 8620231 = 8620284
  • 67 + 8620217 = 8620284
  • 73 + 8620211 = 8620284
  • 97 + 8620187 = 8620284
  • 151 + 8620133 = 8620284
  • 163 + 8620121 = 8620284

Showing the first eight; more decompositions exist.
