Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502358, here are decompositions:

5 + 31502353 = 31502358
29 + 31502329 = 31502358
47 + 31502311 = 31502358
71 + 31502287 = 31502358
79 + 31502279 = 31502358
89 + 31502269 = 31502358
197 + 31502161 = 31502358
211 + 31502147 = 31502358

Showing the first eight; more decompositions exist.
