Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618030, here are decompositions:

37 + 8617993 = 8618030
97 + 8617933 = 8618030
103 + 8617927 = 8618030
193 + 8617837 = 8618030
277 + 8617753 = 8618030
331 + 8617699 = 8618030
349 + 8617681 = 8618030
613 + 8617417 = 8618030

Showing the first eight; more decompositions exist.
