Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562226, here are decompositions:

13 + 31562213 = 31562226
89 + 31562137 = 31562226
107 + 31562119 = 31562226
109 + 31562117 = 31562226
127 + 31562099 = 31562226
173 + 31562053 = 31562226
193 + 31562033 = 31562226
233 + 31561993 = 31562226

Showing the first eight; more decompositions exist.
