Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500594, here are decompositions:

5 + 31500589 = 31500594
107 + 31500487 = 31500594
131 + 31500463 = 31500594
137 + 31500457 = 31500594
211 + 31500383 = 31500594
227 + 31500367 = 31500594
233 + 31500361 = 31500594
241 + 31500353 = 31500594

Showing the first eight; more decompositions exist.
