Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717442, here are decompositions:

53 + 8717389 = 8717442
89 + 8717353 = 8717442
101 + 8717341 = 8717442
113 + 8717329 = 8717442
179 + 8717263 = 8717442
229 + 8717213 = 8717442
241 + 8717201 = 8717442
271 + 8717171 = 8717442

Showing the first eight; more decompositions exist.
