Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627934, here are decompositions:

3 + 31627931 = 31627934
7 + 31627927 = 31627934
31 + 31627903 = 31627934
73 + 31627861 = 31627934
181 + 31627753 = 31627934
307 + 31627627 = 31627934
367 + 31627567 = 31627934
397 + 31627537 = 31627934

Showing the first eight; more decompositions exist.
