Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178604, here are decompositions:

3 + 178601 = 178604
7 + 178597 = 178604
37 + 178567 = 178604
43 + 178561 = 178604
67 + 178537 = 178604
73 + 178531 = 178604
103 + 178501 = 178604
157 + 178447 = 178604

Showing the first eight; more decompositions exist.
