Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42172, here are decompositions:

3 + 42169 = 42172
41 + 42131 = 42172
71 + 42101 = 42172
83 + 42089 = 42172
89 + 42083 = 42172
101 + 42071 = 42172
149 + 42023 = 42172
173 + 41999 = 42172

Showing the first eight; more decompositions exist.
