Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638602, here are decompositions:

19 + 8638583 = 8638602
59 + 8638543 = 8638602
131 + 8638471 = 8638602
139 + 8638463 = 8638602
149 + 8638453 = 8638602
151 + 8638451 = 8638602
191 + 8638411 = 8638602
199 + 8638403 = 8638602

Showing the first eight; more decompositions exist.
