Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648290, here are decompositions:

23 + 8648267 = 8648290
179 + 8648111 = 8648290
191 + 8648099 = 8648290
197 + 8648093 = 8648290
257 + 8648033 = 8648290
293 + 8647997 = 8648290
311 + 8647979 = 8648290
353 + 8647937 = 8648290

Showing the first eight; more decompositions exist.
