Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188922, here are decompositions:

11 + 188911 = 188922
31 + 188891 = 188922
53 + 188869 = 188922
59 + 188863 = 188922
61 + 188861 = 188922
79 + 188843 = 188922
89 + 188833 = 188922
131 + 188791 = 188922

Showing the first eight; more decompositions exist.
