Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944440, here are decompositions:

11 + 944429 = 944440
23 + 944417 = 944440
41 + 944399 = 944440
47 + 944393 = 944440
53 + 944387 = 944440
71 + 944369 = 944440
131 + 944309 = 944440
179 + 944261 = 944440

Showing the first eight; more decompositions exist.
