Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748820, here are decompositions:

53 + 8748767 = 8748820
89 + 8748731 = 8748820
107 + 8748713 = 8748820
167 + 8748653 = 8748820
173 + 8748647 = 8748820
233 + 8748587 = 8748820
239 + 8748581 = 8748820
257 + 8748563 = 8748820

Showing the first eight; more decompositions exist.
