Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642550, here are decompositions:

17 + 8642533 = 8642550
31 + 8642519 = 8642550
41 + 8642509 = 8642550
43 + 8642507 = 8642550
61 + 8642489 = 8642550
83 + 8642467 = 8642550
97 + 8642453 = 8642550
101 + 8642449 = 8642550

Showing the first eight; more decompositions exist.
