Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745078, here are decompositions:

7 + 8745071 = 8745078
11 + 8745067 = 8745078
47 + 8745031 = 8745078
59 + 8745019 = 8745078
61 + 8745017 = 8745078
109 + 8744969 = 8745078
127 + 8744951 = 8745078
137 + 8744941 = 8745078

Showing the first eight; more decompositions exist.
