Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448838, here are decompositions:

  • 17 + 31448821 = 31448838
  • 97 + 31448741 = 31448838
  • 131 + 31448707 = 31448838
  • 139 + 31448699 = 31448838
  • 191 + 31448647 = 31448838
  • 199 + 31448639 = 31448838
  • 251 + 31448587 = 31448838
  • 257 + 31448581 = 31448838

Showing the first eight; more decompositions exist.
