Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748138, here are decompositions:

  • 29 + 8748109 = 8748138
  • 41 + 8748097 = 8748138
  • 107 + 8748031 = 8748138
  • 127 + 8748011 = 8748138
  • 137 + 8748001 = 8748138
  • 151 + 8747987 = 8748138
  • 167 + 8747971 = 8748138
  • 181 + 8747957 = 8748138

Showing the first eight; more decompositions exist.
