Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42380, here are decompositions:

7 + 42373 = 42380
31 + 42349 = 42380
43 + 42337 = 42380
73 + 42307 = 42380
97 + 42283 = 42380
157 + 42223 = 42380
193 + 42187 = 42380
199 + 42181 = 42380

Showing the first eight; more decompositions exist.
