Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42154, here are decompositions:

23 + 42131 = 42154
53 + 42101 = 42154
71 + 42083 = 42154
83 + 42071 = 42154
131 + 42023 = 42154
137 + 42017 = 42154
173 + 41981 = 42154
197 + 41957 = 42154

Showing the first eight; more decompositions exist.
