Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529524, here are decompositions:

3 + 31529521 = 31529524
17 + 31529507 = 31529524
53 + 31529471 = 31529524
251 + 31529273 = 31529524
281 + 31529243 = 31529524
311 + 31529213 = 31529524
443 + 31529081 = 31529524
557 + 31528967 = 31529524

Showing the first eight; more decompositions exist.
