Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463600, here are decompositions:

  • 13 + 31463587 = 31463600
  • 67 + 31463533 = 31463600
  • 73 + 31463527 = 31463600
  • 193 + 31463407 = 31463600
  • 211 + 31463389 = 31463600
  • 271 + 31463329 = 31463600
  • 283 + 31463317 = 31463600
  • 331 + 31463269 = 31463600

Showing the first eight; more decompositions exist.
