Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590964, here are decompositions:

5 + 31590959 = 31590964
23 + 31590941 = 31590964
47 + 31590917 = 31590964
71 + 31590893 = 31590964
131 + 31590833 = 31590964
173 + 31590791 = 31590964
227 + 31590737 = 31590964
233 + 31590731 = 31590964

Showing the first eight; more decompositions exist.
