Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681244, here are decompositions:

  • 23 + 8681221 = 8681244
  • 31 + 8681213 = 8681244
  • 37 + 8681207 = 8681244
  • 53 + 8681191 = 8681244
  • 67 + 8681177 = 8681244
  • 113 + 8681131 = 8681244
  • 127 + 8681117 = 8681244
  • 167 + 8681077 = 8681244

Showing the first eight; more decompositions exist.
