Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536544, here are decompositions:

5 + 31536539 = 31536544
23 + 31536521 = 31536544
191 + 31536353 = 31536544
197 + 31536347 = 31536544
251 + 31536293 = 31536544
257 + 31536287 = 31536544
317 + 31536227 = 31536544
383 + 31536161 = 31536544

Showing the first eight; more decompositions exist.
