Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647374, here are decompositions:

5 + 8647369 = 8647374
7 + 8647367 = 8647374
97 + 8647277 = 8647374
101 + 8647273 = 8647374
181 + 8647193 = 8647374
191 + 8647183 = 8647374
193 + 8647181 = 8647374
251 + 8647123 = 8647374

Showing the first eight; more decompositions exist.
