Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749904, here are decompositions:

13 + 8749891 = 8749904
67 + 8749837 = 8749904
151 + 8749753 = 8749904
277 + 8749627 = 8749904
487 + 8749417 = 8749904
547 + 8749357 = 8749904
661 + 8749243 = 8749904
1051 + 8748853 = 8749904

Showing the first eight; more decompositions exist.
