Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590966, here are decompositions:

7 + 31590959 = 31590966
23 + 31590943 = 31590966
37 + 31590929 = 31590966
59 + 31590907 = 31590966
67 + 31590899 = 31590966
73 + 31590893 = 31590966
79 + 31590887 = 31590966
89 + 31590877 = 31590966

Showing the first eight; more decompositions exist.
