Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724338, here are decompositions:

  • 19 + 8724319 = 8724338
  • 37 + 8724301 = 8724338
  • 79 + 8724259 = 8724338
  • 97 + 8724241 = 8724338
  • 157 + 8724181 = 8724338
  • 199 + 8724139 = 8724338
  • 211 + 8724127 = 8724338
  • 409 + 8723929 = 8724338

Showing the first eight; more decompositions exist.
