Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690218, here are decompositions:

41 + 8690177 = 8690218
101 + 8690117 = 8690218
149 + 8690069 = 8690218
239 + 8689979 = 8690218
269 + 8689949 = 8690218
401 + 8689817 = 8690218
419 + 8689799 = 8690218
491 + 8689727 = 8690218

Showing the first eight; more decompositions exist.
