Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590976, here are decompositions:

17 + 31590959 = 31590976
47 + 31590929 = 31590976
59 + 31590917 = 31590976
83 + 31590893 = 31590976
89 + 31590887 = 31590976
173 + 31590803 = 31590976
239 + 31590737 = 31590976
293 + 31590683 = 31590976

Showing the first eight; more decompositions exist.
