Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712072, here are decompositions:

  • 13 + 8712059 = 8712072
  • 43 + 8712029 = 8712072
  • 53 + 8712019 = 8712072
  • 101 + 8711971 = 8712072
  • 139 + 8711933 = 8712072
  • 151 + 8711921 = 8712072
  • 223 + 8711849 = 8712072
  • 251 + 8711821 = 8712072

Showing the first eight; more decompositions exist.
