Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613428, here are decompositions:

7 + 8613421 = 8613428
37 + 8613391 = 8613428
79 + 8613349 = 8613428
199 + 8613229 = 8613428
337 + 8613091 = 8613428
409 + 8613019 = 8613428
487 + 8612941 = 8613428
661 + 8612767 = 8613428

Showing the first eight; more decompositions exist.
