Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644222, here are decompositions:

131 + 8644091 = 8644222
173 + 8644049 = 8644222
263 + 8643959 = 8644222
269 + 8643953 = 8644222
281 + 8643941 = 8644222
383 + 8643839 = 8644222
401 + 8643821 = 8644222
443 + 8643779 = 8644222

Showing the first eight; more decompositions exist.
