Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506522, here are decompositions:

11 + 31506511 = 31506522
43 + 31506479 = 31506522
79 + 31506443 = 31506522
101 + 31506421 = 31506522
149 + 31506373 = 31506522
163 + 31506359 = 31506522
191 + 31506331 = 31506522
211 + 31506311 = 31506522

Showing the first eight; more decompositions exist.
