Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748726, here are decompositions:

13 + 8748713 = 8748726
17 + 8748709 = 8748726
53 + 8748673 = 8748726
73 + 8748653 = 8748726
79 + 8748647 = 8748726
83 + 8748643 = 8748726
127 + 8748599 = 8748726
137 + 8748589 = 8748726

Showing the first eight; more decompositions exist.
