Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531062, here are decompositions:

5 + 31531057 = 31531062
61 + 31531001 = 31531062
83 + 31530979 = 31531062
89 + 31530973 = 31531062
103 + 31530959 = 31531062
229 + 31530833 = 31531062
263 + 31530799 = 31531062
349 + 31530713 = 31531062

Showing the first eight; more decompositions exist.
