Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522276, here are decompositions:

29 + 31522247 = 31522276
47 + 31522229 = 31522276
173 + 31522103 = 31522276
257 + 31522019 = 31522276
263 + 31522013 = 31522276
389 + 31521887 = 31522276
563 + 31521713 = 31522276
593 + 31521683 = 31522276

Showing the first eight; more decompositions exist.
