Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644242, here are decompositions:

11 + 8644231 = 8644242
29 + 8644213 = 8644242
71 + 8644171 = 8644242
151 + 8644091 = 8644242
181 + 8644061 = 8644242
193 + 8644049 = 8644242
223 + 8644019 = 8644242
251 + 8643991 = 8644242

Showing the first eight; more decompositions exist.
