Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969638, here are decompositions:

79 + 969559 = 969638
157 + 969481 = 969638
181 + 969457 = 969638
337 + 969301 = 969638
367 + 969271 = 969638
379 + 969259 = 969638
457 + 969181 = 969638
499 + 969139 = 969638

Showing the first eight; more decompositions exist.
