Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748732, here are decompositions:

19 + 8748713 = 8748732
23 + 8748709 = 8748732
59 + 8748673 = 8748732
79 + 8748653 = 8748732
89 + 8748643 = 8748732
131 + 8748601 = 8748732
149 + 8748583 = 8748732
151 + 8748581 = 8748732

Showing the first eight; more decompositions exist.
