Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571062, here are decompositions:

23 + 31571039 = 31571062
41 + 31571021 = 31571062
53 + 31571009 = 31571062
101 + 31570961 = 31571062
113 + 31570949 = 31571062
233 + 31570829 = 31571062
251 + 31570811 = 31571062
353 + 31570709 = 31571062

Showing the first eight; more decompositions exist.
