Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949442, here are decompositions:

3 + 949439 = 949442
19 + 949423 = 949442
61 + 949381 = 949442
139 + 949303 = 949442
181 + 949261 = 949442
199 + 949243 = 949442
229 + 949213 = 949442
271 + 949171 = 949442

Showing the first eight; more decompositions exist.
