Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529658, here are decompositions:

7 + 31529651 = 31529658
29 + 31529629 = 31529658
101 + 31529557 = 31529658
107 + 31529551 = 31529658
137 + 31529521 = 31529658
151 + 31529507 = 31529658
179 + 31529479 = 31529658
211 + 31529447 = 31529658

Showing the first eight; more decompositions exist.
