Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722904, here are decompositions:

13 + 8722891 = 8722904
193 + 8722711 = 8722904
283 + 8722621 = 8722904
433 + 8722471 = 8722904
457 + 8722447 = 8722904
571 + 8722333 = 8722904
601 + 8722303 = 8722904
607 + 8722297 = 8722904

Showing the first eight; more decompositions exist.
