Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742474, here are decompositions:

  • 5 + 8742469 = 8742474
  • 11 + 8742463 = 8742474
  • 53 + 8742421 = 8742474
  • 73 + 8742401 = 8742474
  • 107 + 8742367 = 8742474
  • 127 + 8742347 = 8742474
  • 157 + 8742317 = 8742474
  • 211 + 8742263 = 8742474

Showing the first eight; more decompositions exist.
