Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626218, here are decompositions:

37 + 8626181 = 8626218
59 + 8626159 = 8626218
79 + 8626139 = 8626218
89 + 8626129 = 8626218
109 + 8626109 = 8626218
151 + 8626067 = 8626218
157 + 8626061 = 8626218
239 + 8625979 = 8626218

Showing the first eight; more decompositions exist.
