Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618446, here are decompositions:

3 + 8618443 = 8618446
17 + 8618429 = 8618446
59 + 8618387 = 8618446
107 + 8618339 = 8618446
149 + 8618297 = 8618446
173 + 8618273 = 8618446
233 + 8618213 = 8618446
359 + 8618087 = 8618446

Showing the first eight; more decompositions exist.
