Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531054, here are decompositions:

53 + 31531001 = 31531054
227 + 31530827 = 31531054
257 + 31530797 = 31531054
281 + 31530773 = 31531054
353 + 31530701 = 31531054
461 + 31530593 = 31531054
557 + 31530497 = 31531054
617 + 31530437 = 31531054

Showing the first eight; more decompositions exist.
