Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745042, here are decompositions:

11 + 8745031 = 8745042
23 + 8745019 = 8745042
73 + 8744969 = 8745042
101 + 8744941 = 8745042
113 + 8744929 = 8745042
139 + 8744903 = 8745042
151 + 8744891 = 8745042
181 + 8744861 = 8745042

Showing the first eight; more decompositions exist.
