Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620430, here are decompositions:

  • 37 + 8620393 = 8620430
  • 61 + 8620369 = 8620430
  • 103 + 8620327 = 8620430
  • 163 + 8620267 = 8620430
  • 199 + 8620231 = 8620430
  • 211 + 8620219 = 8620430
  • 241 + 8620189 = 8620430
  • 271 + 8620159 = 8620430

Showing the first eight; more decompositions exist.
