Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621732, here are decompositions:

79 + 8621653 = 8621732
109 + 8621623 = 8621732
151 + 8621581 = 8621732
181 + 8621551 = 8621732
241 + 8621491 = 8621732
433 + 8621299 = 8621732
523 + 8621209 = 8621732
631 + 8621101 = 8621732

Showing the first eight; more decompositions exist.
