Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 944220, here are decompositions:

29 + 944191 = 944220
41 + 944179 = 944220
59 + 944161 = 944220
71 + 944149 = 944220
73 + 944147 = 944220
83 + 944137 = 944220
97 + 944123 = 944220
149 + 944071 = 944220

Showing the first eight; more decompositions exist.
