Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642568, here are decompositions:

59 + 8642509 = 8642568
61 + 8642507 = 8642568
79 + 8642489 = 8642568
101 + 8642467 = 8642568
139 + 8642429 = 8642568
239 + 8642329 = 8642568
331 + 8642237 = 8642568
379 + 8642189 = 8642568

Showing the first eight; more decompositions exist.
