Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986778, here are decompositions:

  • 11 + 986767 = 986778
  • 19 + 986759 = 986778
  • 29 + 986749 = 986778
  • 41 + 986737 = 986778
  • 59 + 986719 = 986778
  • 61 + 986717 = 986778
  • 71 + 986707 = 986778
  • 137 + 986641 = 986778

Showing the first eight; more decompositions exist.
