Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529998, here are decompositions:

29 + 31529969 = 31529998
107 + 31529891 = 31529998
179 + 31529819 = 31529998
281 + 31529717 = 31529998
317 + 31529681 = 31529998
347 + 31529651 = 31529998
431 + 31529567 = 31529998
491 + 31529507 = 31529998

Showing the first eight; more decompositions exist.
