Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748774, here are decompositions:

7 + 8748767 = 8748774
31 + 8748743 = 8748774
43 + 8748731 = 8748774
61 + 8748713 = 8748774
101 + 8748673 = 8748774
127 + 8748647 = 8748774
131 + 8748643 = 8748774
173 + 8748601 = 8748774

Showing the first eight; more decompositions exist.
