Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949142, here are decompositions:

13 + 949129 = 949142
31 + 949111 = 949142
109 + 949033 = 949142
199 + 948943 = 949142
241 + 948901 = 949142
421 + 948721 = 949142
673 + 948469 = 949142
739 + 948403 = 949142

Showing the first eight; more decompositions exist.
