Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530474, here are decompositions:

  • 23 + 31530451 = 31530474
  • 37 + 31530437 = 31530474
  • 83 + 31530391 = 31530474
  • 97 + 31530377 = 31530474
  • 127 + 31530347 = 31530474
  • 163 + 31530311 = 31530474
  • 181 + 31530293 = 31530474
  • 263 + 31530211 = 31530474

Showing the first eight; more decompositions exist.
