Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724384, here are decompositions:

  • 7 + 8724377 = 8724384
  • 13 + 8724371 = 8724384
  • 37 + 8724347 = 8724384
  • 61 + 8724323 = 8724384
  • 73 + 8724311 = 8724384
  • 83 + 8724301 = 8724384
  • 101 + 8724283 = 8724384
  • 131 + 8724253 = 8724384

Showing the first eight; more decompositions exist.
