Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628402, here are decompositions:

  • 19 + 8628383 = 8628402
  • 43 + 8628359 = 8628402
  • 53 + 8628349 = 8628402
  • 109 + 8628293 = 8628402
  • 131 + 8628271 = 8628402
  • 199 + 8628203 = 8628402
  • 229 + 8628173 = 8628402
  • 241 + 8628161 = 8628402

Showing the first eight; more decompositions exist.
