Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748666, here are decompositions:

13 + 8748653 = 8748666
19 + 8748647 = 8748666
23 + 8748643 = 8748666
67 + 8748599 = 8748666
79 + 8748587 = 8748666
83 + 8748583 = 8748666
103 + 8748563 = 8748666
163 + 8748503 = 8748666

Showing the first eight; more decompositions exist.
