Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722928, here are decompositions:

37 + 8722891 = 8722928
139 + 8722789 = 8722928
307 + 8722621 = 8722928
457 + 8722471 = 8722928
499 + 8722429 = 8722928
631 + 8722297 = 8722928
691 + 8722237 = 8722928
757 + 8722171 = 8722928

Showing the first eight; more decompositions exist.
