Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178922, here are decompositions:

13 + 178909 = 178922
19 + 178903 = 178922
103 + 178819 = 178922
109 + 178813 = 178922
229 + 178693 = 178922
241 + 178681 = 178922
283 + 178639 = 178922
313 + 178609 = 178922

Showing the first eight; more decompositions exist.
