Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717290, here are decompositions:

3 + 8717287 = 8717290
17 + 8717273 = 8717290
89 + 8717201 = 8717290
167 + 8717123 = 8717290
173 + 8717117 = 8717290
269 + 8717021 = 8717290
293 + 8716997 = 8717290
347 + 8716943 = 8717290

Showing the first eight; more decompositions exist.
