Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681208, here are decompositions:

  • 17 + 8681191 = 8681208
  • 31 + 8681177 = 8681208
  • 79 + 8681129 = 8681208
  • 97 + 8681111 = 8681208
  • 131 + 8681077 = 8681208
  • 149 + 8681059 = 8681208
  • 199 + 8681009 = 8681208
  • 257 + 8680951 = 8681208

Showing the first eight; more decompositions exist.
