Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188022, here are decompositions:

5 + 188017 = 188022
11 + 188011 = 188022
59 + 187963 = 188022
71 + 187951 = 188022
101 + 187921 = 188022
113 + 187909 = 188022
139 + 187883 = 188022
151 + 187871 = 188022

Showing the first eight; more decompositions exist.
