Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520934, here are decompositions:

17 + 31520917 = 31520934
23 + 31520911 = 31520934
37 + 31520897 = 31520934
73 + 31520861 = 31520934
83 + 31520851 = 31520934
97 + 31520837 = 31520934
173 + 31520761 = 31520934
233 + 31520701 = 31520934

Showing the first eight; more decompositions exist.
