Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642586, here are decompositions:

5 + 8642581 = 8642586
19 + 8642567 = 8642586
53 + 8642533 = 8642586
67 + 8642519 = 8642586
79 + 8642507 = 8642586
97 + 8642489 = 8642586
137 + 8642449 = 8642586
157 + 8642429 = 8642586

Showing the first eight; more decompositions exist.
