Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80660, here are decompositions:

3 + 80657 = 80660
31 + 80629 = 80660
61 + 80599 = 80660
103 + 80557 = 80660
211 + 80449 = 80660
313 + 80347 = 80660
331 + 80329 = 80660
373 + 80287 = 80660

Showing the first eight; more decompositions exist.
