Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623346, here are decompositions:

  • 3 + 31623343 = 31623346
  • 89 + 31623257 = 31623346
  • 137 + 31623209 = 31623346
  • 173 + 31623173 = 31623346
  • 179 + 31623167 = 31623346
  • 233 + 31623113 = 31623346
  • 509 + 31622837 = 31623346
  • 569 + 31622777 = 31623346

Showing the first eight; more decompositions exist.
