Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745012, here are decompositions:

43 + 8744969 = 8745012
61 + 8744951 = 8745012
71 + 8744941 = 8745012
83 + 8744929 = 8745012
103 + 8744909 = 8745012
109 + 8744903 = 8745012
151 + 8744861 = 8745012
179 + 8744833 = 8745012

Showing the first eight; more decompositions exist.
