Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531498, here are decompositions:

41 + 31531457 = 31531498
197 + 31531301 = 31531498
227 + 31531271 = 31531498
281 + 31531217 = 31531498
359 + 31531139 = 31531498
419 + 31531079 = 31531498
521 + 31530977 = 31531498
701 + 31530797 = 31531498

Showing the first eight; more decompositions exist.
