Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529674, here are decompositions:

3 + 31529671 = 31529674
5 + 31529669 = 31529674
23 + 31529651 = 31529674
107 + 31529567 = 31529674
167 + 31529507 = 31529674
227 + 31529447 = 31529674
353 + 31529321 = 31529674
401 + 31529273 = 31529674

Showing the first eight; more decompositions exist.
