Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529814, here are decompositions:

31 + 31529783 = 31529814
97 + 31529717 = 31529814
137 + 31529677 = 31529814
163 + 31529651 = 31529814
191 + 31529623 = 31529814
257 + 31529557 = 31529814
263 + 31529551 = 31529814
293 + 31529521 = 31529814

Showing the first eight; more decompositions exist.
