Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630442, here are decompositions:

  • 131 + 8630311 = 8630442
  • 151 + 8630291 = 8630442
  • 173 + 8630269 = 8630442
  • 193 + 8630249 = 8630442
  • 199 + 8630243 = 8630442
  • 211 + 8630231 = 8630442
  • 241 + 8630201 = 8630442
  • 251 + 8630191 = 8630442

Showing the first eight; more decompositions exist.
