Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474864, here are decompositions:

  • 101 + 31474763 = 31474864
  • 131 + 31474733 = 31474864
  • 173 + 31474691 = 31474864
  • 191 + 31474673 = 31474864
  • 263 + 31474601 = 31474864
  • 293 + 31474571 = 31474864
  • 383 + 31474481 = 31474864
  • 431 + 31474433 = 31474864

Showing the first eight; more decompositions exist.
