Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76686, here are decompositions:

7 + 76679 = 76686
13 + 76673 = 76686
19 + 76667 = 76686
37 + 76649 = 76686
79 + 76607 = 76686
83 + 76603 = 76686
89 + 76597 = 76686
107 + 76579 = 76686

Showing the first eight; more decompositions exist.
