Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715442, here are decompositions:

11 + 8715431 = 8715442
41 + 8715401 = 8715442
59 + 8715383 = 8715442
173 + 8715269 = 8715442
179 + 8715263 = 8715442
233 + 8715209 = 8715442
251 + 8715191 = 8715442
383 + 8715059 = 8715442

Showing the first eight; more decompositions exist.
