Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529952, here are decompositions:

19 + 31529933 = 31529952
29 + 31529923 = 31529952
53 + 31529899 = 31529952
61 + 31529891 = 31529952
71 + 31529881 = 31529952
109 + 31529843 = 31529952
271 + 31529681 = 31529952
281 + 31529671 = 31529952

Showing the first eight; more decompositions exist.
