Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742850, here are decompositions:

3 + 8742847 = 8742850
29 + 8742821 = 8742850
71 + 8742779 = 8742850
173 + 8742677 = 8742850
197 + 8742653 = 8742850
227 + 8742623 = 8742850
353 + 8742497 = 8742850
401 + 8742449 = 8742850

Showing the first eight; more decompositions exist.
