Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590996, here are decompositions:

5 + 31590991 = 31590996
37 + 31590959 = 31590996
53 + 31590943 = 31590996
67 + 31590929 = 31590996
79 + 31590917 = 31590996
89 + 31590907 = 31590996
97 + 31590899 = 31590996
103 + 31590893 = 31590996

Showing the first eight; more decompositions exist.
