Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536550, here are decompositions:

11 + 31536539 = 31536550
29 + 31536521 = 31536550
167 + 31536383 = 31536550
191 + 31536359 = 31536550
197 + 31536353 = 31536550
257 + 31536293 = 31536550
263 + 31536287 = 31536550
347 + 31536203 = 31536550

Showing the first eight; more decompositions exist.
