Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446832, here are decompositions:

  • 71 + 31446761 = 31446832
  • 83 + 31446749 = 31446832
  • 89 + 31446743 = 31446832
  • 191 + 31446641 = 31446832
  • 239 + 31446593 = 31446832
  • 269 + 31446563 = 31446832
  • 491 + 31446341 = 31446832
  • 503 + 31446329 = 31446832

Showing the first eight; more decompositions exist.
