Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626220, here are decompositions:

61 + 8626159 = 8626220
79 + 8626141 = 8626220
157 + 8626063 = 8626220
223 + 8625997 = 8626220
241 + 8625979 = 8626220
307 + 8625913 = 8626220
331 + 8625889 = 8626220
367 + 8625853 = 8626220

Showing the first eight; more decompositions exist.
