Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546756, here are decompositions:

47 + 31546709 = 31546756
173 + 31546583 = 31546756
419 + 31546337 = 31546756
557 + 31546199 = 31546756
569 + 31546187 = 31546756
743 + 31546013 = 31546756
797 + 31545959 = 31546756
1013 + 31545743 = 31546756

Showing the first eight; more decompositions exist.
