Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718722, here are decompositions:

13 + 8718709 = 8718722
73 + 8718649 = 8718722
151 + 8718571 = 8718722
283 + 8718439 = 8718722
373 + 8718349 = 8718722
379 + 8718343 = 8718722
409 + 8718313 = 8718722
421 + 8718301 = 8718722

Showing the first eight; more decompositions exist.
