Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600642, here are decompositions:

3 + 8600639 = 8600642
13 + 8600629 = 8600642
109 + 8600533 = 8600642
151 + 8600491 = 8600642
181 + 8600461 = 8600642
283 + 8600359 = 8600642
409 + 8600233 = 8600642
499 + 8600143 = 8600642

Showing the first eight; more decompositions exist.
