Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596522, here are decompositions:

11 + 31596511 = 31596522
103 + 31596419 = 31596522
109 + 31596413 = 31596522
131 + 31596391 = 31596522
211 + 31596311 = 31596522
229 + 31596293 = 31596522
313 + 31596209 = 31596522
359 + 31596163 = 31596522

Showing the first eight; more decompositions exist.
