Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178612, here are decompositions:

3 + 178609 = 178612
11 + 178601 = 178612
41 + 178571 = 178612
53 + 178559 = 178612
131 + 178481 = 178612
173 + 178439 = 178612
251 + 178361 = 178612
263 + 178349 = 178612

Showing the first eight; more decompositions exist.
