Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529826, here are decompositions:

7 + 31529819 = 31529826
43 + 31529783 = 31529826
109 + 31529717 = 31529826
149 + 31529677 = 31529826
157 + 31529669 = 31529826
197 + 31529629 = 31529826
233 + 31529593 = 31529826
269 + 31529557 = 31529826

Showing the first eight; more decompositions exist.
