Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42378, here are decompositions:

5 + 42373 = 42378
19 + 42359 = 42378
29 + 42349 = 42378
41 + 42337 = 42378
47 + 42331 = 42378
71 + 42307 = 42378
79 + 42299 = 42378
97 + 42281 = 42378

Showing the first eight; more decompositions exist.
