Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530944, here are decompositions:

43 + 31530901 = 31530944
103 + 31530841 = 31530944
241 + 31530703 = 31530944
283 + 31530661 = 31530944
307 + 31530637 = 31530944
337 + 31530607 = 31530944
373 + 31530571 = 31530944
421 + 31530523 = 31530944

Showing the first eight; more decompositions exist.
