Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646040, here are decompositions:

23 + 8646017 = 8646040
59 + 8645981 = 8646040
113 + 8645927 = 8646040
191 + 8645849 = 8646040
251 + 8645789 = 8646040
281 + 8645759 = 8646040
311 + 8645729 = 8646040
353 + 8645687 = 8646040

Showing the first eight; more decompositions exist.
