Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582764, here are decompositions:

7 + 31582757 = 31582764
97 + 31582667 = 31582764
131 + 31582633 = 31582764
137 + 31582627 = 31582764
151 + 31582613 = 31582764
163 + 31582601 = 31582764
211 + 31582553 = 31582764
233 + 31582531 = 31582764

Showing the first eight; more decompositions exist.
