Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488526, here are decompositions:

29 + 31488497 = 31488526
197 + 31488329 = 31488526
227 + 31488299 = 31488526
233 + 31488293 = 31488526
269 + 31488257 = 31488526
389 + 31488137 = 31488526
467 + 31488059 = 31488526
569 + 31487957 = 31488526

Showing the first eight; more decompositions exist.
