Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529704, here are decompositions:

23 + 31529681 = 31529704
53 + 31529651 = 31529704
137 + 31529567 = 31529704
197 + 31529507 = 31529704
233 + 31529471 = 31529704
257 + 31529447 = 31529704
383 + 31529321 = 31529704
431 + 31529273 = 31529704

Showing the first eight; more decompositions exist.
