Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562154, here are decompositions:

17 + 31562137 = 31562154
37 + 31562117 = 31562154
47 + 31562107 = 31562154
61 + 31562093 = 31562154
97 + 31562057 = 31562154
101 + 31562053 = 31562154
131 + 31562023 = 31562154
137 + 31562017 = 31562154

Showing the first eight; more decompositions exist.
