Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728924, here are decompositions:

3 + 8728921 = 8728924
23 + 8728901 = 8728924
41 + 8728883 = 8728924
101 + 8728823 = 8728924
137 + 8728787 = 8728924
167 + 8728757 = 8728924
233 + 8728691 = 8728924
317 + 8728607 = 8728924

Showing the first eight; more decompositions exist.
