Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15078, here are decompositions:

  • 5 + 15073 = 15078
  • 17 + 15061 = 15078
  • 47 + 15031 = 15078
  • 61 + 15017 = 15078
  • 109 + 14969 = 15078
  • 127 + 14951 = 15078
  • 131 + 14947 = 15078
  • 139 + 14939 = 15078

Showing the first eight; more decompositions exist.
