Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541822, here are decompositions:

  • 61 + 31541761 = 31541822
  • 163 + 31541659 = 31541822
  • 211 + 31541611 = 31541822
  • 241 + 31541581 = 31541822
  • 313 + 31541509 = 31541822
  • 373 + 31541449 = 31541822
  • 421 + 31541401 = 31541822
  • 463 + 31541359 = 31541822

Showing the first eight; more decompositions exist.
