Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562146, here are decompositions:

29 + 31562117 = 31562146
47 + 31562099 = 31562146
53 + 31562093 = 31562146
89 + 31562057 = 31562146
113 + 31562033 = 31562146
137 + 31562009 = 31562146
173 + 31561973 = 31562146
179 + 31561967 = 31562146

Showing the first eight; more decompositions exist.
