Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562112, here are decompositions:

5 + 31562107 = 31562112
13 + 31562099 = 31562112
19 + 31562093 = 31562112
59 + 31562053 = 31562112
79 + 31562033 = 31562112
89 + 31562023 = 31562112
103 + 31562009 = 31562112
139 + 31561973 = 31562112

Showing the first eight; more decompositions exist.
