Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626988, here are decompositions:

61 + 8626927 = 8626988
127 + 8626861 = 8626988
157 + 8626831 = 8626988
211 + 8626777 = 8626988
241 + 8626747 = 8626988
367 + 8626621 = 8626988
439 + 8626549 = 8626988
571 + 8626417 = 8626988

Showing the first eight; more decompositions exist.
