Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728996, here are decompositions:

53 + 8728943 = 8728996
113 + 8728883 = 8728996
173 + 8728823 = 8728996
239 + 8728757 = 8728996
317 + 8728679 = 8728996
347 + 8728649 = 8728996
389 + 8728607 = 8728996
569 + 8728427 = 8728996

Showing the first eight; more decompositions exist.
