Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669228, here are decompositions:

157 + 8669071 = 8669228
277 + 8668951 = 8669228
331 + 8668897 = 8669228
397 + 8668831 = 8669228
487 + 8668741 = 8669228
541 + 8668687 = 8669228
619 + 8668609 = 8669228
709 + 8668519 = 8669228

Showing the first eight; more decompositions exist.
