Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502710, here are decompositions:

11 + 31502699 = 31502710
23 + 31502687 = 31502710
149 + 31502561 = 31502710
227 + 31502483 = 31502710
251 + 31502459 = 31502710
269 + 31502441 = 31502710
347 + 31502363 = 31502710
431 + 31502279 = 31502710

Showing the first eight; more decompositions exist.
