Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658146, here are decompositions:

37 + 8658109 = 8658146
43 + 8658103 = 8658146
103 + 8658043 = 8658146
163 + 8657983 = 8658146
223 + 8657923 = 8658146
313 + 8657833 = 8658146
379 + 8657767 = 8658146
577 + 8657569 = 8658146

Showing the first eight; more decompositions exist.
