Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562166, here are decompositions:

29 + 31562137 = 31562166
47 + 31562119 = 31562166
59 + 31562107 = 31562166
67 + 31562099 = 31562166
73 + 31562093 = 31562166
109 + 31562057 = 31562166
113 + 31562053 = 31562166
149 + 31562017 = 31562166

Showing the first eight; more decompositions exist.
