Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178508, here are decompositions:

7 + 178501 = 178508
19 + 178489 = 178508
61 + 178447 = 178508
67 + 178441 = 178508
157 + 178351 = 178508
181 + 178327 = 178508
277 + 178231 = 178508
367 + 178141 = 178508

Showing the first eight; more decompositions exist.
