Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531714, here are decompositions:

47 + 31531667 = 31531714
191 + 31531523 = 31531714
257 + 31531457 = 31531714
293 + 31531421 = 31531714
311 + 31531403 = 31531714
443 + 31531271 = 31531714
821 + 31530893 = 31531714
881 + 31530833 = 31531714

Showing the first eight; more decompositions exist.
