Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742790, here are decompositions:

3 + 8742787 = 8742790
11 + 8742779 = 8742790
101 + 8742689 = 8742790
113 + 8742677 = 8742790
137 + 8742653 = 8742790
167 + 8742623 = 8742790
239 + 8742551 = 8742790
293 + 8742497 = 8742790

Showing the first eight; more decompositions exist.
