Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562244, here are decompositions:

13 + 31562231 = 31562244
31 + 31562213 = 31562244
107 + 31562137 = 31562244
127 + 31562117 = 31562244
137 + 31562107 = 31562244
151 + 31562093 = 31562244
191 + 31562053 = 31562244
211 + 31562033 = 31562244

Showing the first eight; more decompositions exist.
