Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527742, here are decompositions:

  • 41 + 31527701 = 31527742
  • 53 + 31527689 = 31527742
  • 83 + 31527659 = 31527742
  • 173 + 31527569 = 31527742
  • 251 + 31527491 = 31527742
  • 353 + 31527389 = 31527742
  • 419 + 31527323 = 31527742
  • 431 + 31527311 = 31527742

Showing the first eight; more decompositions exist.
