Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42312, here are decompositions:

5 + 42307 = 42312
13 + 42299 = 42312
19 + 42293 = 42312
29 + 42283 = 42312
31 + 42281 = 42312
73 + 42239 = 42312
89 + 42223 = 42312
103 + 42209 = 42312

Showing the first eight; more decompositions exist.
