Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742922, here are decompositions:

3 + 8742919 = 8742922
5 + 8742917 = 8742922
101 + 8742821 = 8742922
233 + 8742689 = 8742922
269 + 8742653 = 8742922
521 + 8742401 = 8742922
563 + 8742359 = 8742922
569 + 8742353 = 8742922

Showing the first eight; more decompositions exist.
