Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690290, here are decompositions:

23 + 8690267 = 8690290
113 + 8690177 = 8690290
173 + 8690117 = 8690290
197 + 8690093 = 8690290
227 + 8690063 = 8690290
293 + 8689997 = 8690290
311 + 8689979 = 8690290
347 + 8689943 = 8690290

Showing the first eight; more decompositions exist.
