Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623490, here are decompositions:

  • 61 + 8623429 = 8623490
  • 67 + 8623423 = 8623490
  • 97 + 8623393 = 8623490
  • 151 + 8623339 = 8623490
  • 199 + 8623291 = 8623490
  • 229 + 8623261 = 8623490
  • 241 + 8623249 = 8623490
  • 277 + 8623213 = 8623490

Showing the first eight; more decompositions exist.
