Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748660, here are decompositions:

7 + 8748653 = 8748660
13 + 8748647 = 8748660
17 + 8748643 = 8748660
59 + 8748601 = 8748660
61 + 8748599 = 8748660
71 + 8748589 = 8748660
73 + 8748587 = 8748660
79 + 8748581 = 8748660

Showing the first eight; more decompositions exist.
