Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562202, here are decompositions:

83 + 31562119 = 31562202
103 + 31562099 = 31562202
109 + 31562093 = 31562202
149 + 31562053 = 31562202
179 + 31562023 = 31562202
193 + 31562009 = 31562202
229 + 31561973 = 31562202
233 + 31561969 = 31562202

Showing the first eight; more decompositions exist.
