Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749006, here are decompositions:

5 + 8749001 = 8749006
17 + 8748989 = 8749006
53 + 8748953 = 8749006
113 + 8748893 = 8749006
179 + 8748827 = 8749006
239 + 8748767 = 8749006
263 + 8748743 = 8749006
293 + 8748713 = 8749006

Showing the first eight; more decompositions exist.
