Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944420, here are decompositions:

3 + 944417 = 944420
31 + 944389 = 944420
157 + 944263 = 944420
163 + 944257 = 944420
181 + 944239 = 944420
229 + 944191 = 944420
241 + 944179 = 944420
271 + 944149 = 944420

Showing the first eight; more decompositions exist.
