Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42386, here are decompositions:

7 + 42379 = 42386
13 + 42373 = 42386
37 + 42349 = 42386
79 + 42307 = 42386
103 + 42283 = 42386
163 + 42223 = 42386
193 + 42193 = 42386
199 + 42187 = 42386

Showing the first eight; more decompositions exist.
