Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588214, here are decompositions:

  • 13 + 31588201 = 31588214
  • 43 + 31588171 = 31588214
  • 127 + 31588087 = 31588214
  • 211 + 31588003 = 31588214
  • 271 + 31587943 = 31588214
  • 337 + 31587877 = 31588214
  • 397 + 31587817 = 31588214
  • 421 + 31587793 = 31588214

Showing the first eight; more decompositions exist.
