Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742810, here are decompositions:

23 + 8742787 = 8742810
31 + 8742779 = 8742810
71 + 8742739 = 8742810
137 + 8742673 = 8742810
157 + 8742653 = 8742810
173 + 8742637 = 8742810
233 + 8742577 = 8742810
239 + 8742571 = 8742810

Showing the first eight; more decompositions exist.
