Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748656, here are decompositions:

3 + 8748653 = 8748656
13 + 8748643 = 8748656
67 + 8748589 = 8748656
73 + 8748583 = 8748656
157 + 8748499 = 8748656
193 + 8748463 = 8748656
379 + 8748277 = 8748656
457 + 8748199 = 8748656

Showing the first eight; more decompositions exist.
