Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690618, here are decompositions:

7 + 8690611 = 8690618
19 + 8690599 = 8690618
61 + 8690557 = 8690618
67 + 8690551 = 8690618
241 + 8690377 = 8690618
397 + 8690221 = 8690618
499 + 8690119 = 8690618
577 + 8690041 = 8690618

Showing the first eight; more decompositions exist.
