Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562124, here are decompositions:

5 + 31562119 = 31562124
7 + 31562117 = 31562124
17 + 31562107 = 31562124
31 + 31562093 = 31562124
67 + 31562057 = 31562124
71 + 31562053 = 31562124
101 + 31562023 = 31562124
107 + 31562017 = 31562124

Showing the first eight; more decompositions exist.
