Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717490, here are decompositions:

97 + 8717393 = 8717490
101 + 8717389 = 8717490
137 + 8717353 = 8717490
149 + 8717341 = 8717490
167 + 8717323 = 8717490
227 + 8717263 = 8717490
251 + 8717239 = 8717490
277 + 8717213 = 8717490

Showing the first eight; more decompositions exist.
