Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643626, here are decompositions:

7 + 8643619 = 8643626
37 + 8643589 = 8643626
139 + 8643487 = 8643626
193 + 8643433 = 8643626
283 + 8643343 = 8643626
613 + 8643013 = 8643626
769 + 8642857 = 8643626
787 + 8642839 = 8643626

Showing the first eight; more decompositions exist.
