Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748746, here are decompositions:

3 + 8748743 = 8748746
7 + 8748739 = 8748746
37 + 8748709 = 8748746
73 + 8748673 = 8748746
103 + 8748643 = 8748746
157 + 8748589 = 8748746
163 + 8748583 = 8748746
277 + 8748469 = 8748746

Showing the first eight; more decompositions exist.
