Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606438, here are decompositions:

7 + 8606431 = 8606438
37 + 8606401 = 8606438
97 + 8606341 = 8606438
109 + 8606329 = 8606438
151 + 8606287 = 8606438
157 + 8606281 = 8606438
241 + 8606197 = 8606438
397 + 8606041 = 8606438

Showing the first eight; more decompositions exist.
