Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644090, here are decompositions:

29 + 8644061 = 8644090
41 + 8644049 = 8644090
71 + 8644019 = 8644090
131 + 8643959 = 8644090
137 + 8643953 = 8644090
149 + 8643941 = 8644090
167 + 8643923 = 8644090
197 + 8643893 = 8644090

Showing the first eight; more decompositions exist.
