Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644562, here are decompositions:

61 + 8644501 = 8644562
109 + 8644453 = 8644562
331 + 8644231 = 8644562
349 + 8644213 = 8644562
439 + 8644123 = 8644562
571 + 8643991 = 8644562
643 + 8643919 = 8644562
673 + 8643889 = 8644562

Showing the first eight; more decompositions exist.
