Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529824, here are decompositions:

5 + 31529819 = 31529824
41 + 31529783 = 31529824
107 + 31529717 = 31529824
173 + 31529651 = 31529824
257 + 31529567 = 31529824
317 + 31529507 = 31529824
353 + 31529471 = 31529824
503 + 31529321 = 31529824

Showing the first eight; more decompositions exist.
