Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608442, here are decompositions:

13 + 8608429 = 8608442
19 + 8608423 = 8608442
43 + 8608399 = 8608442
109 + 8608333 = 8608442
151 + 8608291 = 8608442
181 + 8608261 = 8608442
211 + 8608231 = 8608442
433 + 8608009 = 8608442

Showing the first eight; more decompositions exist.
