Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590936, here are decompositions:

5 + 31590931 = 31590936
7 + 31590929 = 31590936
19 + 31590917 = 31590936
29 + 31590907 = 31590936
37 + 31590899 = 31590936
43 + 31590893 = 31590936
59 + 31590877 = 31590936
89 + 31590847 = 31590936

Showing the first eight; more decompositions exist.
