Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615148, here are decompositions:

  • 11 + 8615137 = 8615148
  • 97 + 8615051 = 8615148
  • 131 + 8615017 = 8615148
  • 181 + 8614967 = 8615148
  • 197 + 8614951 = 8615148
  • 281 + 8614867 = 8615148
  • 307 + 8614841 = 8615148
  • 317 + 8614831 = 8615148

Showing the first eight; more decompositions exist.
