Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546228, here are decompositions:

  • 11 + 31546217 = 31546228
  • 29 + 31546199 = 31546228
  • 41 + 31546187 = 31546228
  • 47 + 31546181 = 31546228
  • 269 + 31545959 = 31546228
  • 479 + 31545749 = 31546228
  • 491 + 31545737 = 31546228
  • 587 + 31545641 = 31546228

Showing the first eight; more decompositions exist.
