Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80672, here are decompositions:

3 + 80669 = 80672
43 + 80629 = 80672
61 + 80611 = 80672
73 + 80599 = 80672
181 + 80491 = 80672
199 + 80473 = 80672
223 + 80449 = 80672
331 + 80341 = 80672

Showing the first eight; more decompositions exist.
