Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643022, here are decompositions:

71 + 8642951 = 8643022
83 + 8642939 = 8643022
173 + 8642849 = 8643022
389 + 8642633 = 8643022
431 + 8642591 = 8643022
503 + 8642519 = 8643022
569 + 8642453 = 8643022
593 + 8642429 = 8643022

Showing the first eight; more decompositions exist.
