Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545474, here are decompositions:

  • 5 + 31545469 = 31545474
  • 67 + 31545407 = 31545474
  • 73 + 31545401 = 31545474
  • 83 + 31545391 = 31545474
  • 101 + 31545373 = 31545474
  • 131 + 31545343 = 31545474
  • 151 + 31545323 = 31545474
  • 157 + 31545317 = 31545474

Showing the first eight; more decompositions exist.
