Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7278, here are decompositions:

  • 31 + 7247 = 7278
  • 41 + 7237 = 7278
  • 59 + 7219 = 7278
  • 67 + 7211 = 7278
  • 71 + 7207 = 7278
  • 101 + 7177 = 7278
  • 127 + 7151 = 7278
  • 149 + 7129 = 7278

Showing the first eight; more decompositions exist.
