Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742886, here are decompositions:

29 + 8742857 = 8742886
107 + 8742779 = 8742886
197 + 8742689 = 8742886
233 + 8742653 = 8742886
263 + 8742623 = 8742886
389 + 8742497 = 8742886
569 + 8742317 = 8742886
809 + 8742077 = 8742886

Showing the first eight; more decompositions exist.
