Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486352, here are decompositions:

  • 3 + 31486349 = 31486352
  • 13 + 31486339 = 31486352
  • 151 + 31486201 = 31486352
  • 223 + 31486129 = 31486352
  • 229 + 31486123 = 31486352
  • 379 + 31485973 = 31486352
  • 421 + 31485931 = 31486352
  • 463 + 31485889 = 31486352

Showing the first eight; more decompositions exist.
