Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621764, here are decompositions:

17 + 8621747 = 8621764
71 + 8621693 = 8621764
83 + 8621681 = 8621764
311 + 8621453 = 8621764
353 + 8621411 = 8621764
521 + 8621243 = 8621764
563 + 8621201 = 8621764
617 + 8621147 = 8621764

Showing the first eight; more decompositions exist.
