Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643764, here are decompositions:

7 + 8643757 = 8643764
43 + 8643721 = 8643764
67 + 8643697 = 8643764
277 + 8643487 = 8643764
307 + 8643457 = 8643764
331 + 8643433 = 8643764
397 + 8643367 = 8643764
421 + 8643343 = 8643764

Showing the first eight; more decompositions exist.
