Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644228, here are decompositions:

41 + 8644187 = 8644228
71 + 8644157 = 8644228
137 + 8644091 = 8644228
167 + 8644061 = 8644228
179 + 8644049 = 8644228
269 + 8643959 = 8644228
389 + 8643839 = 8644228
431 + 8643797 = 8644228

Showing the first eight; more decompositions exist.
