Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618622, here are decompositions:

29 + 8618593 = 8618622
31 + 8618591 = 8618622
41 + 8618581 = 8618622
139 + 8618483 = 8618622
179 + 8618443 = 8618622
193 + 8618429 = 8618622
283 + 8618339 = 8618622
293 + 8618329 = 8618622

Showing the first eight; more decompositions exist.
