Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137922, here are decompositions:

11 + 137911 = 137922
13 + 137909 = 137922
53 + 137869 = 137922
73 + 137849 = 137922
131 + 137791 = 137922
151 + 137771 = 137922
179 + 137743 = 137922
199 + 137723 = 137922

Showing the first eight; more decompositions exist.
