Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40278, here are decompositions:

  • 37 + 40241 = 40278
  • 41 + 40237 = 40278
  • 47 + 40231 = 40278
  • 89 + 40189 = 40278
  • 101 + 40177 = 40278
  • 109 + 40169 = 40278
  • 127 + 40151 = 40278
  • 149 + 40129 = 40278

Showing the first eight; more decompositions exist.
