Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529838, here are decompositions:

19 + 31529819 = 31529838
89 + 31529749 = 31529838
157 + 31529681 = 31529838
167 + 31529671 = 31529838
271 + 31529567 = 31529838
281 + 31529557 = 31529838
317 + 31529521 = 31529838
331 + 31529507 = 31529838

Showing the first eight; more decompositions exist.
