Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502338, here are decompositions:

5 + 31502333 = 31502338
59 + 31502279 = 31502338
149 + 31502189 = 31502338
191 + 31502147 = 31502338
239 + 31502099 = 31502338
359 + 31501979 = 31502338
401 + 31501937 = 31502338
431 + 31501907 = 31502338

Showing the first eight; more decompositions exist.
