Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493058, here are decompositions:

5 + 31493053 = 31493058
11 + 31493047 = 31493058
19 + 31493039 = 31493058
29 + 31493029 = 31493058
41 + 31493017 = 31493058
61 + 31492997 = 31493058
67 + 31492991 = 31493058
137 + 31492921 = 31493058

Showing the first eight; more decompositions exist.
