Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501252, here are decompositions:

5 + 31501247 = 31501252
23 + 31501229 = 31501252
53 + 31501199 = 31501252
191 + 31501061 = 31501252
311 + 31500941 = 31501252
353 + 31500899 = 31501252
389 + 31500863 = 31501252
443 + 31500809 = 31501252

Showing the first eight; more decompositions exist.
