Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576522, here are decompositions:

11 + 31576511 = 31576522
83 + 31576439 = 31576522
113 + 31576409 = 31576522
149 + 31576373 = 31576522
233 + 31576289 = 31576522
239 + 31576283 = 31576522
269 + 31576253 = 31576522
281 + 31576241 = 31576522

Showing the first eight; more decompositions exist.
