Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716940, here are decompositions:

79 + 8716861 = 8716940
97 + 8716843 = 8716940
157 + 8716783 = 8716940
181 + 8716759 = 8716940
277 + 8716663 = 8716940
313 + 8716627 = 8716940
373 + 8716567 = 8716940
409 + 8716531 = 8716940

Showing the first eight; more decompositions exist.
