Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529484, here are decompositions:

5 + 31529479 = 31529484
13 + 31529471 = 31529484
37 + 31529447 = 31529484
53 + 31529431 = 31529484
71 + 31529413 = 31529484
131 + 31529353 = 31529484
137 + 31529347 = 31529484
163 + 31529321 = 31529484

Showing the first eight; more decompositions exist.
