Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742862, here are decompositions:

5 + 8742857 = 8742862
41 + 8742821 = 8742862
83 + 8742779 = 8742862
173 + 8742689 = 8742862
239 + 8742623 = 8742862
311 + 8742551 = 8742862
461 + 8742401 = 8742862
503 + 8742359 = 8742862

Showing the first eight; more decompositions exist.
