Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626928, here are decompositions:

  • 29 + 31626899 = 31626928
  • 59 + 31626869 = 31626928
  • 71 + 31626857 = 31626928
  • 89 + 31626839 = 31626928
  • 101 + 31626827 = 31626928
  • 131 + 31626797 = 31626928
  • 239 + 31626689 = 31626928
  • 467 + 31626461 = 31626928

Showing the first eight; more decompositions exist.
