Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748784, here are decompositions:

17 + 8748767 = 8748784
41 + 8748743 = 8748784
53 + 8748731 = 8748784
71 + 8748713 = 8748784
131 + 8748653 = 8748784
137 + 8748647 = 8748784
197 + 8748587 = 8748784
281 + 8748503 = 8748784

Showing the first eight; more decompositions exist.
