Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493064, here are decompositions:

7 + 31493057 = 31493064
11 + 31493053 = 31493064
17 + 31493047 = 31493064
47 + 31493017 = 31493064
67 + 31492997 = 31493064
73 + 31492991 = 31493064
101 + 31492963 = 31493064
131 + 31492933 = 31493064

Showing the first eight; more decompositions exist.
