Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618090, here are decompositions:

3 + 8618087 = 8618090
7 + 8618083 = 8618090
31 + 8618059 = 8618090
43 + 8618047 = 8618090
97 + 8617993 = 8618090
157 + 8617933 = 8618090
163 + 8617927 = 8618090
337 + 8617753 = 8618090

Showing the first eight; more decompositions exist.
