Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724542, here are decompositions:

  • 31 + 8724511 = 8724542
  • 223 + 8724319 = 8724542
  • 241 + 8724301 = 8724542
  • 283 + 8724259 = 8724542
  • 373 + 8724169 = 8724542
  • 613 + 8723929 = 8724542
  • 643 + 8723899 = 8724542
  • 691 + 8723851 = 8724542

Showing the first eight; more decompositions exist.
