Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485752, here are decompositions:

3 + 31485749 = 31485752
31 + 31485721 = 31485752
211 + 31485541 = 31485752
373 + 31485379 = 31485752
433 + 31485319 = 31485752
439 + 31485313 = 31485752
631 + 31485121 = 31485752
673 + 31485079 = 31485752

Showing the first eight; more decompositions exist.
