Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502332, here are decompositions:

3 + 31502329 = 31502332
53 + 31502279 = 31502332
89 + 31502243 = 31502332
149 + 31502183 = 31502332
233 + 31502099 = 31502332
353 + 31501979 = 31502332
419 + 31501913 = 31502332
509 + 31501823 = 31502332

Showing the first eight; more decompositions exist.
