Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542522, here are decompositions:

13 + 31542509 = 31542522
43 + 31542479 = 31542522
83 + 31542439 = 31542522
103 + 31542419 = 31542522
131 + 31542391 = 31542522
149 + 31542373 = 31542522
163 + 31542359 = 31542522
181 + 31542341 = 31542522

Showing the first eight; more decompositions exist.
