Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502926, here are decompositions:

3 + 31502923 = 31502926
29 + 31502897 = 31502926
149 + 31502777 = 31502926
227 + 31502699 = 31502926
239 + 31502687 = 31502926
443 + 31502483 = 31502926
467 + 31502459 = 31502926
563 + 31502363 = 31502926

Showing the first eight; more decompositions exist.
