Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647394, here are decompositions:

3 + 8647391 = 8647394
163 + 8647231 = 8647394
211 + 8647183 = 8647394
271 + 8647123 = 8647394
331 + 8647063 = 8647394
367 + 8647027 = 8647394
373 + 8647021 = 8647394
433 + 8646961 = 8647394

Showing the first eight; more decompositions exist.
