Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546990, here are decompositions:

3 + 31546987 = 31546990
53 + 31546937 = 31546990
173 + 31546817 = 31546990
191 + 31546799 = 31546990
269 + 31546721 = 31546990
281 + 31546709 = 31546990
353 + 31546637 = 31546990
389 + 31546601 = 31546990

Showing the first eight; more decompositions exist.
