Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531654, here are decompositions:

5 + 31531649 = 31531654
131 + 31531523 = 31531654
197 + 31531457 = 31531654
233 + 31531421 = 31531654
251 + 31531403 = 31531654
353 + 31531301 = 31531654
383 + 31531271 = 31531654
491 + 31531163 = 31531654

Showing the first eight; more decompositions exist.
