Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748744, here are decompositions:

5 + 8748739 = 8748744
13 + 8748731 = 8748744
31 + 8748713 = 8748744
71 + 8748673 = 8748744
97 + 8748647 = 8748744
101 + 8748643 = 8748744
157 + 8748587 = 8748744
163 + 8748581 = 8748744

Showing the first eight; more decompositions exist.
