Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749764, here are decompositions:

11 + 8749753 = 8749764
13 + 8749751 = 8749764
31 + 8749733 = 8749764
113 + 8749651 = 8749764
137 + 8749627 = 8749764
151 + 8749613 = 8749764
157 + 8749607 = 8749764
193 + 8749571 = 8749764

Showing the first eight; more decompositions exist.
