Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722994, here are decompositions:

3 + 8722991 = 8722994
13 + 8722981 = 8722994
103 + 8722891 = 8722994
283 + 8722711 = 8722994
373 + 8722621 = 8722994
523 + 8722471 = 8722994
547 + 8722447 = 8722994
571 + 8722423 = 8722994

Showing the first eight; more decompositions exist.
