Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658442, here are decompositions:

11 + 8658431 = 8658442
29 + 8658413 = 8658442
59 + 8658383 = 8658442
71 + 8658371 = 8658442
113 + 8658329 = 8658442
239 + 8658203 = 8658442
281 + 8658161 = 8658442
383 + 8658059 = 8658442

Showing the first eight; more decompositions exist.
