Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42190, here are decompositions:

3 + 42187 = 42190
11 + 42179 = 42190
59 + 42131 = 42190
89 + 42101 = 42190
101 + 42089 = 42190
107 + 42083 = 42190
167 + 42023 = 42190
173 + 42017 = 42190

Showing the first eight; more decompositions exist.
