Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562214, here are decompositions:

97 + 31562117 = 31562214
107 + 31562107 = 31562214
157 + 31562057 = 31562214
181 + 31562033 = 31562214
191 + 31562023 = 31562214
197 + 31562017 = 31562214
241 + 31561973 = 31562214
311 + 31561903 = 31562214

Showing the first eight; more decompositions exist.
