Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502350, here are decompositions:

17 + 31502333 = 31502350
71 + 31502279 = 31502350
107 + 31502243 = 31502350
137 + 31502213 = 31502350
167 + 31502183 = 31502350
251 + 31502099 = 31502350
443 + 31501907 = 31502350
569 + 31501781 = 31502350

Showing the first eight; more decompositions exist.
