Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621824, here are decompositions:

5 + 8621819 = 8621824
131 + 8621693 = 8621824
347 + 8621477 = 8621824
587 + 8621237 = 8621824
641 + 8621183 = 8621824
677 + 8621147 = 8621824
773 + 8621051 = 8621824
881 + 8620943 = 8621824

Showing the first eight; more decompositions exist.
