Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529734, here are decompositions:

17 + 31529717 = 31529734
53 + 31529681 = 31529734
83 + 31529651 = 31529734
167 + 31529567 = 31529734
227 + 31529507 = 31529734
263 + 31529471 = 31529734
461 + 31529273 = 31529734
491 + 31529243 = 31529734

Showing the first eight; more decompositions exist.
