Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494066, here are decompositions:

13 + 31494053 = 31494066
67 + 31493999 = 31494066
83 + 31493983 = 31494066
139 + 31493927 = 31494066
157 + 31493909 = 31494066
167 + 31493899 = 31494066
277 + 31493789 = 31494066
283 + 31493783 = 31494066

Showing the first eight; more decompositions exist.
