Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757240, here are decompositions:

17 + 8757223 = 8757240
31 + 8757209 = 8757240
53 + 8757187 = 8757240
61 + 8757179 = 8757240
67 + 8757173 = 8757240
97 + 8757143 = 8757240
109 + 8757131 = 8757240
113 + 8757127 = 8757240

Showing the first eight; more decompositions exist.
