Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749012, here are decompositions:

5 + 8749007 = 8749012
11 + 8749001 = 8749012
23 + 8748989 = 8749012
59 + 8748953 = 8749012
131 + 8748881 = 8749012
191 + 8748821 = 8749012
269 + 8748743 = 8749012
281 + 8748731 = 8749012

Showing the first eight; more decompositions exist.
