Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742892, here are decompositions:

5 + 8742887 = 8742892
71 + 8742821 = 8742892
113 + 8742779 = 8742892
239 + 8742653 = 8742892
269 + 8742623 = 8742892
443 + 8742449 = 8742892
491 + 8742401 = 8742892
881 + 8742011 = 8742892

Showing the first eight; more decompositions exist.
