Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562110, here are decompositions:

3 + 31562107 = 31562110
11 + 31562099 = 31562110
17 + 31562093 = 31562110
53 + 31562057 = 31562110
101 + 31562009 = 31562110
137 + 31561973 = 31562110
191 + 31561919 = 31562110
263 + 31561847 = 31562110

Showing the first eight; more decompositions exist.
