Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748690, here are decompositions:

17 + 8748673 = 8748690
37 + 8748653 = 8748690
43 + 8748647 = 8748690
47 + 8748643 = 8748690
89 + 8748601 = 8748690
101 + 8748589 = 8748690
103 + 8748587 = 8748690
107 + 8748583 = 8748690

Showing the first eight; more decompositions exist.
