Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562056, here are decompositions:

3 + 31562053 = 31562056
23 + 31562033 = 31562056
47 + 31562009 = 31562056
83 + 31561973 = 31562056
89 + 31561967 = 31562056
137 + 31561919 = 31562056
233 + 31561823 = 31562056
359 + 31561697 = 31562056

Showing the first eight; more decompositions exist.
