Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752490, here are decompositions:

13 + 8752477 = 8752490
73 + 8752417 = 8752490
151 + 8752339 = 8752490
163 + 8752327 = 8752490
181 + 8752309 = 8752490
199 + 8752291 = 8752490
283 + 8752207 = 8752490
337 + 8752153 = 8752490

Showing the first eight; more decompositions exist.
