Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562234, here are decompositions:

3 + 31562231 = 31562234
97 + 31562137 = 31562234
127 + 31562107 = 31562234
181 + 31562053 = 31562234
211 + 31562023 = 31562234
241 + 31561993 = 31562234
307 + 31561927 = 31562234
331 + 31561903 = 31562234

Showing the first eight; more decompositions exist.
