Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944388, here are decompositions:

19 + 944369 = 944388
59 + 944329 = 944388
79 + 944309 = 944388
127 + 944261 = 944388
131 + 944257 = 944388
149 + 944239 = 944388
197 + 944191 = 944388
227 + 944161 = 944388

Showing the first eight; more decompositions exist.
