Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624080, here are decompositions:

  • 11 + 31624069 = 31624080
  • 67 + 31624013 = 31624080
  • 79 + 31624001 = 31624080
  • 97 + 31623983 = 31624080
  • 101 + 31623979 = 31624080
  • 109 + 31623971 = 31624080
  • 113 + 31623967 = 31624080
  • 127 + 31623953 = 31624080

Showing the first eight; more decompositions exist.
