Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529454, here are decompositions:

7 + 31529447 = 31529454
23 + 31529431 = 31529454
41 + 31529413 = 31529454
101 + 31529353 = 31529454
107 + 31529347 = 31529454
181 + 31529273 = 31529454
197 + 31529257 = 31529454
211 + 31529243 = 31529454

Showing the first eight; more decompositions exist.
