Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189122, here are decompositions:

61 + 189061 = 189122
79 + 189043 = 189122
103 + 189019 = 189122
139 + 188983 = 189122
181 + 188941 = 189122
211 + 188911 = 189122
331 + 188791 = 189122
421 + 188701 = 189122

Showing the first eight; more decompositions exist.
