Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749620, here are decompositions:

7 + 8749613 = 8749620
13 + 8749607 = 8749620
17 + 8749603 = 8749620
31 + 8749589 = 8749620
41 + 8749579 = 8749620
71 + 8749549 = 8749620
151 + 8749469 = 8749620
163 + 8749457 = 8749620

Showing the first eight; more decompositions exist.
