Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529460, here are decompositions:

13 + 31529447 = 31529460
29 + 31529431 = 31529460
47 + 31529413 = 31529460
101 + 31529359 = 31529460
107 + 31529353 = 31529460
113 + 31529347 = 31529460
139 + 31529321 = 31529460
181 + 31529279 = 31529460

Showing the first eight; more decompositions exist.
