Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615168, here are decompositions:

  • 7 + 8615161 = 8615168
  • 19 + 8615149 = 8615168
  • 31 + 8615137 = 8615168
  • 151 + 8615017 = 8615168
  • 181 + 8614987 = 8615168
  • 229 + 8614939 = 8615168
  • 337 + 8614831 = 8615168
  • 379 + 8614789 = 8615168

Showing the first eight; more decompositions exist.
