Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749756, here are decompositions:

3 + 8749753 = 8749756
5 + 8749751 = 8749756
23 + 8749733 = 8749756
149 + 8749607 = 8749756
167 + 8749589 = 8749756
317 + 8749439 = 8749756
419 + 8749337 = 8749756
557 + 8749199 = 8749756

Showing the first eight; more decompositions exist.
