Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752290, here are decompositions:

17 + 8752273 = 8752290
37 + 8752253 = 8752290
59 + 8752231 = 8752290
83 + 8752207 = 8752290
89 + 8752201 = 8752290
103 + 8752187 = 8752290
109 + 8752181 = 8752290
137 + 8752153 = 8752290

Showing the first eight; more decompositions exist.
