Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526750, here are decompositions:

  • 19 + 31526731 = 31526750
  • 37 + 31526713 = 31526750
  • 61 + 31526689 = 31526750
  • 103 + 31526647 = 31526750
  • 223 + 31526527 = 31526750
  • 331 + 31526419 = 31526750
  • 379 + 31526371 = 31526750
  • 433 + 31526317 = 31526750

Showing the first eight; more decompositions exist.
