Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644442, here are decompositions:

3 + 8644439 = 8644442
181 + 8644261 = 8644442
199 + 8644243 = 8644442
211 + 8644231 = 8644442
229 + 8644213 = 8644442
271 + 8644171 = 8644442
523 + 8643919 = 8644442
769 + 8643673 = 8644442

Showing the first eight; more decompositions exist.
