Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749460, here are decompositions:

3 + 8749457 = 8749460
37 + 8749423 = 8749460
43 + 8749417 = 8749460
103 + 8749357 = 8749460
151 + 8749309 = 8749460
241 + 8749219 = 8749460
373 + 8749087 = 8749460
487 + 8748973 = 8749460

Showing the first eight; more decompositions exist.
