Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529452, here are decompositions:

5 + 31529447 = 31529452
131 + 31529321 = 31529452
173 + 31529279 = 31529452
179 + 31529273 = 31529452
233 + 31529219 = 31529452
239 + 31529213 = 31529452
599 + 31528853 = 31529452
641 + 31528811 = 31529452

Showing the first eight; more decompositions exist.
