Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179678, here are decompositions:

7 + 179671 = 179678
19 + 179659 = 179678
97 + 179581 = 179678
151 + 179527 = 179678
181 + 179497 = 179678
199 + 179479 = 179678
241 + 179437 = 179678
271 + 179407 = 179678

Showing the first eight; more decompositions exist.
