Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529796, here are decompositions:

13 + 31529783 = 31529796
47 + 31529749 = 31529796
79 + 31529717 = 31529796
127 + 31529669 = 31529796
167 + 31529629 = 31529796
173 + 31529623 = 31529796
229 + 31529567 = 31529796
239 + 31529557 = 31529796

Showing the first eight; more decompositions exist.
