Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571174, here are decompositions:

7 + 31571167 = 31571174
31 + 31571143 = 31571174
127 + 31571047 = 31571174
157 + 31571017 = 31571174
181 + 31570993 = 31571174
307 + 31570867 = 31571174
331 + 31570843 = 31571174
571 + 31570603 = 31571174

Showing the first eight; more decompositions exist.
