Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42188, here are decompositions:

7 + 42181 = 42188
19 + 42169 = 42188
31 + 42157 = 42188
127 + 42061 = 42188
229 + 41959 = 42188
241 + 41947 = 42188
277 + 41911 = 42188
337 + 41851 = 42188

Showing the first eight; more decompositions exist.
