Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642806, here are decompositions:

59 + 8642747 = 8642806
83 + 8642723 = 8642806
173 + 8642633 = 8642806
239 + 8642567 = 8642806
317 + 8642489 = 8642806
353 + 8642453 = 8642806
503 + 8642303 = 8642806
569 + 8642237 = 8642806

Showing the first eight; more decompositions exist.
