Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002478, here are decompositions:

  • 11 + 1002467 = 1002478
  • 101 + 1002377 = 1002478
  • 131 + 1002347 = 1002478
  • 137 + 1002341 = 1002478
  • 179 + 1002299 = 1002478
  • 251 + 1002227 = 1002478
  • 401 + 1002077 = 1002478
  • 461 + 1002017 = 1002478

Showing the first eight; more decompositions exist.
