Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502950, here are decompositions:

23 + 31502927 = 31502950
53 + 31502897 = 31502950
173 + 31502777 = 31502950
251 + 31502699 = 31502950
263 + 31502687 = 31502950
389 + 31502561 = 31502950
461 + 31502489 = 31502950
467 + 31502483 = 31502950

Showing the first eight; more decompositions exist.
