Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547462, here are decompositions:

3 + 31547459 = 31547462
13 + 31547449 = 31547462
181 + 31547281 = 31547462
571 + 31546891 = 31547462
601 + 31546861 = 31547462
619 + 31546843 = 31547462
631 + 31546831 = 31547462
673 + 31546789 = 31547462

Showing the first eight; more decompositions exist.
