Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606442, here are decompositions:

11 + 8606431 = 8606442
29 + 8606413 = 8606442
41 + 8606401 = 8606442
79 + 8606363 = 8606442
101 + 8606341 = 8606442
113 + 8606329 = 8606442
149 + 8606293 = 8606442
179 + 8606263 = 8606442

Showing the first eight; more decompositions exist.
