Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531060, here are decompositions:

3 + 31531057 = 31531060
59 + 31531001 = 31531060
83 + 31530977 = 31531060
101 + 31530959 = 31531060
167 + 31530893 = 31531060
227 + 31530833 = 31531060
233 + 31530827 = 31531060
263 + 31530797 = 31531060

Showing the first eight; more decompositions exist.
