Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493046, here are decompositions:

7 + 31493039 = 31493046
17 + 31493029 = 31493046
29 + 31493017 = 31493046
37 + 31493009 = 31493046
83 + 31492963 = 31493046
103 + 31492943 = 31493046
113 + 31492933 = 31493046
139 + 31492907 = 31493046

Showing the first eight; more decompositions exist.
