Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531246, here are decompositions:

29 + 31531217 = 31531246
83 + 31531163 = 31531246
107 + 31531139 = 31531246
167 + 31531079 = 31531246
269 + 31530977 = 31531246
353 + 31530893 = 31531246
419 + 31530827 = 31531246
449 + 31530797 = 31531246

Showing the first eight; more decompositions exist.
