Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42382, here are decompositions:

3 + 42379 = 42382
23 + 42359 = 42382
59 + 42323 = 42382
83 + 42299 = 42382
89 + 42293 = 42382
101 + 42281 = 42382
173 + 42209 = 42382
251 + 42131 = 42382

Showing the first eight; more decompositions exist.
