Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529596, here are decompositions:

3 + 31529593 = 31529596
29 + 31529567 = 31529596
89 + 31529507 = 31529596
149 + 31529447 = 31529596
317 + 31529279 = 31529596
347 + 31529249 = 31529596
353 + 31529243 = 31529596
383 + 31529213 = 31529596

Showing the first eight; more decompositions exist.
