Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486244, here are decompositions:

  • 43 + 31486201 = 31486244
  • 157 + 31486087 = 31486244
  • 211 + 31486033 = 31486244
  • 271 + 31485973 = 31486244
  • 313 + 31485931 = 31486244
  • 373 + 31485871 = 31486244
  • 421 + 31485823 = 31486244
  • 487 + 31485757 = 31486244

Showing the first eight; more decompositions exist.
