Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72106, here are decompositions:

  • 3 + 72103 = 72106
  • 5 + 72101 = 72106
  • 17 + 72089 = 72106
  • 29 + 72077 = 72106
  • 53 + 72053 = 72106
  • 59 + 72047 = 72106
  • 107 + 71999 = 72106
  • 113 + 71993 = 72106

Showing the first eight; more decompositions exist.
