Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178550, here are decompositions:

13 + 178537 = 178550
19 + 178531 = 178550
37 + 178513 = 178550
61 + 178489 = 178550
103 + 178447 = 178550
109 + 178441 = 178550
157 + 178393 = 178550
199 + 178351 = 178550

Showing the first eight; more decompositions exist.
