Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178598, here are decompositions:

31 + 178567 = 178598
37 + 178561 = 178598
61 + 178537 = 178598
67 + 178531 = 178598
97 + 178501 = 178598
109 + 178489 = 178598
151 + 178447 = 178598
157 + 178441 = 178598

Showing the first eight; more decompositions exist.
