Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749788, here are decompositions:

17 + 8749771 = 8749788
37 + 8749751 = 8749788
137 + 8749651 = 8749788
181 + 8749607 = 8749788
199 + 8749589 = 8749788
239 + 8749549 = 8749788
331 + 8749457 = 8749788
337 + 8749451 = 8749788

Showing the first eight; more decompositions exist.
