Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752728, here are decompositions:

11 + 8752717 = 8752728
31 + 8752697 = 8752728
71 + 8752657 = 8752728
109 + 8752619 = 8752728
167 + 8752561 = 8752728
191 + 8752537 = 8752728
197 + 8752531 = 8752728
251 + 8752477 = 8752728

Showing the first eight; more decompositions exist.
