Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493106, here are decompositions:

23 + 31493083 = 31493106
37 + 31493069 = 31493106
53 + 31493053 = 31493106
59 + 31493047 = 31493106
67 + 31493039 = 31493106
89 + 31493017 = 31493106
97 + 31493009 = 31493106
109 + 31492997 = 31493106

Showing the first eight; more decompositions exist.
