Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529698, here are decompositions:

17 + 31529681 = 31529698
29 + 31529669 = 31529698
47 + 31529651 = 31529698
131 + 31529567 = 31529698
191 + 31529507 = 31529698
227 + 31529471 = 31529698
251 + 31529447 = 31529698
419 + 31529279 = 31529698

Showing the first eight; more decompositions exist.
