Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7808, here are decompositions:

  • 19 + 7789 = 7808
  • 67 + 7741 = 7808
  • 109 + 7699 = 7808
  • 127 + 7681 = 7808
  • 139 + 7669 = 7808
  • 271 + 7537 = 7808
  • 331 + 7477 = 7808
  • 349 + 7459 = 7808

Showing the first eight; more decompositions exist.
