Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15088, here are decompositions:

  • 5 + 15083 = 15088
  • 11 + 15077 = 15088
  • 71 + 15017 = 15088
  • 131 + 14957 = 15088
  • 137 + 14951 = 15088
  • 149 + 14939 = 15088
  • 191 + 14897 = 15088
  • 197 + 14891 = 15088

Showing the first eight; more decompositions exist.
