Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618066, here are decompositions:

3 + 8618063 = 8618066
7 + 8618059 = 8618066
19 + 8618047 = 8618066
73 + 8617993 = 8618066
139 + 8617927 = 8618066
229 + 8617837 = 8618066
313 + 8617753 = 8618066
367 + 8617699 = 8618066

Showing the first eight; more decompositions exist.
