Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490782, here are decompositions:

  • 11 + 490771 = 490782
  • 13 + 490769 = 490782
  • 41 + 490741 = 490782
  • 139 + 490643 = 490782
  • 151 + 490631 = 490782
  • 163 + 490619 = 490782
  • 191 + 490591 = 490782
  • 211 + 490571 = 490782

Showing the first eight; more decompositions exist.
