Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730400, here are decompositions:

  • 23 + 8730377 = 8730400
  • 47 + 8730353 = 8730400
  • 59 + 8730341 = 8730400
  • 89 + 8730311 = 8730400
  • 113 + 8730287 = 8730400
  • 131 + 8730269 = 8730400
  • 137 + 8730263 = 8730400
  • 251 + 8730149 = 8730400

Showing the first eight; more decompositions exist.
