Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657962, here are decompositions:

29 + 8657933 = 8657962
59 + 8657903 = 8657962
113 + 8657849 = 8657962
179 + 8657783 = 8657962
191 + 8657771 = 8657962
239 + 8657723 = 8657962
263 + 8657699 = 8657962
281 + 8657681 = 8657962

Showing the first eight; more decompositions exist.
