Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743756, here are decompositions:

3 + 8743753 = 8743756
23 + 8743733 = 8743756
83 + 8743673 = 8743756
167 + 8743589 = 8743756
173 + 8743583 = 8743756
257 + 8743499 = 8743756
347 + 8743409 = 8743756
389 + 8743367 = 8743756

Showing the first eight; more decompositions exist.
