Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627992, here are decompositions:

13 + 31627979 = 31627992
23 + 31627969 = 31627992
31 + 31627961 = 31627992
43 + 31627949 = 31627992
61 + 31627931 = 31627992
89 + 31627903 = 31627992
103 + 31627889 = 31627992
113 + 31627879 = 31627992

Showing the first eight; more decompositions exist.
