Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179386, here are decompositions:

3 + 179383 = 179386
5 + 179381 = 179386
17 + 179369 = 179386
29 + 179357 = 179386
59 + 179327 = 179386
173 + 179213 = 179386
353 + 179033 = 179386
479 + 178907 = 179386

Showing the first eight; more decompositions exist.
