Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722946, here are decompositions:

157 + 8722789 = 8722946
487 + 8722459 = 8722946
499 + 8722447 = 8722946
523 + 8722423 = 8722946
607 + 8722339 = 8722946
613 + 8722333 = 8722946
643 + 8722303 = 8722946
709 + 8722237 = 8722946

Showing the first eight; more decompositions exist.
