Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627996, here are decompositions:

17 + 31627979 = 31627996
47 + 31627949 = 31627996
107 + 31627889 = 31627996
233 + 31627763 = 31627996
269 + 31627727 = 31627996
347 + 31627649 = 31627996
419 + 31627577 = 31627996
677 + 31627319 = 31627996

Showing the first eight; more decompositions exist.
