Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562116, here are decompositions:

17 + 31562099 = 31562116
23 + 31562093 = 31562116
59 + 31562057 = 31562116
83 + 31562033 = 31562116
107 + 31562009 = 31562116
149 + 31561967 = 31562116
197 + 31561919 = 31562116
269 + 31561847 = 31562116

Showing the first eight; more decompositions exist.
