Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717742, here are decompositions:

53 + 8717689 = 8717742
109 + 8717633 = 8717742
151 + 8717591 = 8717742
179 + 8717563 = 8717742
191 + 8717551 = 8717742
211 + 8717531 = 8717742
233 + 8717509 = 8717742
251 + 8717491 = 8717742

Showing the first eight; more decompositions exist.
