Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80618, here are decompositions:

7 + 80611 = 80618
19 + 80599 = 80618
61 + 80557 = 80618
127 + 80491 = 80618
211 + 80407 = 80618
271 + 80347 = 80618
277 + 80341 = 80618
331 + 80287 = 80618

Showing the first eight; more decompositions exist.
