Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672390, here are decompositions:

  • 3 + 8672387 = 8672390
  • 37 + 8672353 = 8672390
  • 43 + 8672347 = 8672390
  • 127 + 8672263 = 8672390
  • 151 + 8672239 = 8672390
  • 229 + 8672161 = 8672390
  • 409 + 8671981 = 8672390
  • 751 + 8671639 = 8672390

Showing the first eight; more decompositions exist.
