Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531134, here are decompositions:

17 + 31531117 = 31531134
71 + 31531063 = 31531134
157 + 31530977 = 31531134
191 + 31530943 = 31531134
233 + 31530901 = 31531134
241 + 31530893 = 31531134
293 + 31530841 = 31531134
307 + 31530827 = 31531134

Showing the first eight; more decompositions exist.
