Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642598, here are decompositions:

7 + 8642591 = 8642598
17 + 8642581 = 8642598
31 + 8642567 = 8642598
79 + 8642519 = 8642598
89 + 8642509 = 8642598
109 + 8642489 = 8642598
131 + 8642467 = 8642598
149 + 8642449 = 8642598

Showing the first eight; more decompositions exist.
