Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80656, here are decompositions:

5 + 80651 = 80656
29 + 80627 = 80656
53 + 80603 = 80656
89 + 80567 = 80656
167 + 80489 = 80656
227 + 80429 = 80656
269 + 80387 = 80656
293 + 80363 = 80656

Showing the first eight; more decompositions exist.
