Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722112, here are decompositions:

  • 13 + 8722099 = 8722112
  • 19 + 8722093 = 8722112
  • 31 + 8722081 = 8722112
  • 79 + 8722033 = 8722112
  • 103 + 8722009 = 8722112
  • 199 + 8721913 = 8722112
  • 229 + 8721883 = 8722112
  • 349 + 8721763 = 8722112

Showing the first eight; more decompositions exist.
