Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643974, here are decompositions:

277 + 8643697 = 8643974
397 + 8643577 = 8643974
487 + 8643487 = 8643974
541 + 8643433 = 8643974
607 + 8643367 = 8643974
631 + 8643343 = 8643974
751 + 8643223 = 8643974
853 + 8643121 = 8643974

Showing the first eight; more decompositions exist.
