Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529416, here are decompositions:

3 + 31529413 = 31529416
137 + 31529279 = 31529416
167 + 31529249 = 31529416
173 + 31529243 = 31529416
197 + 31529219 = 31529416
419 + 31528997 = 31529416
449 + 31528967 = 31529416
563 + 31528853 = 31529416

Showing the first eight; more decompositions exist.
