Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529476, here are decompositions:

5 + 31529471 = 31529476
29 + 31529447 = 31529476
197 + 31529279 = 31529476
227 + 31529249 = 31529476
233 + 31529243 = 31529476
257 + 31529219 = 31529476
263 + 31529213 = 31529476
389 + 31529087 = 31529476

Showing the first eight; more decompositions exist.
