Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604428, here are decompositions:

109 + 8604319 = 8604428
271 + 8604157 = 8604428
277 + 8604151 = 8604428
631 + 8603797 = 8604428
661 + 8603767 = 8604428
727 + 8603701 = 8604428
739 + 8603689 = 8604428
751 + 8603677 = 8604428

Showing the first eight; more decompositions exist.
