Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949220, here are decompositions:

7 + 949213 = 949220
61 + 949159 = 949220
67 + 949153 = 949220
73 + 949147 = 949220
109 + 949111 = 949220
199 + 949021 = 949220
277 + 948943 = 949220
313 + 948907 = 949220

Showing the first eight; more decompositions exist.
