Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42212, here are decompositions:

3 + 42209 = 42212
19 + 42193 = 42212
31 + 42181 = 42212
43 + 42169 = 42212
73 + 42139 = 42212
139 + 42073 = 42212
151 + 42061 = 42212
193 + 42019 = 42212

Showing the first eight; more decompositions exist.
