Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562136, here are decompositions:

17 + 31562119 = 31562136
19 + 31562117 = 31562136
29 + 31562107 = 31562136
37 + 31562099 = 31562136
43 + 31562093 = 31562136
79 + 31562057 = 31562136
83 + 31562053 = 31562136
103 + 31562033 = 31562136

Showing the first eight; more decompositions exist.
