Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179218, here are decompositions:

5 + 179213 = 179218
107 + 179111 = 179218
167 + 179051 = 179218
197 + 179021 = 179218
311 + 178907 = 179218
359 + 178859 = 179218
401 + 178817 = 179218
419 + 178799 = 179218

Showing the first eight; more decompositions exist.
