Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749124, here are decompositions:

3 + 8749121 = 8749124
37 + 8749087 = 8749124
151 + 8748973 = 8749124
271 + 8748853 = 8749124
277 + 8748847 = 8749124
283 + 8748841 = 8749124
313 + 8748811 = 8749124
337 + 8748787 = 8749124

Showing the first eight; more decompositions exist.
