Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644290, here are decompositions:

29 + 8644261 = 8644290
37 + 8644253 = 8644290
47 + 8644243 = 8644290
59 + 8644231 = 8644290
103 + 8644187 = 8644290
167 + 8644123 = 8644290
199 + 8644091 = 8644290
229 + 8644061 = 8644290

Showing the first eight; more decompositions exist.
