Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80664, here are decompositions:

7 + 80657 = 80664
13 + 80651 = 80664
37 + 80627 = 80664
43 + 80621 = 80664
53 + 80611 = 80664
61 + 80603 = 80664
97 + 80567 = 80664
107 + 80557 = 80664

Showing the first eight; more decompositions exist.
