Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478414, here are decompositions:

  • 3 + 31478411 = 31478414
  • 13 + 31478401 = 31478414
  • 43 + 31478371 = 31478414
  • 73 + 31478341 = 31478414
  • 127 + 31478287 = 31478414
  • 241 + 31478173 = 31478414
  • 337 + 31478077 = 31478414
  • 397 + 31478017 = 31478414

Showing the first eight; more decompositions exist.
