Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529764, here are decompositions:

47 + 31529717 = 31529764
83 + 31529681 = 31529764
113 + 31529651 = 31529764
197 + 31529567 = 31529764
257 + 31529507 = 31529764
293 + 31529471 = 31529764
317 + 31529447 = 31529764
443 + 31529321 = 31529764

Showing the first eight; more decompositions exist.
