Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502314, here are decompositions:

3 + 31502311 = 31502314
71 + 31502243 = 31502314
101 + 31502213 = 31502314
131 + 31502183 = 31502314
167 + 31502147 = 31502314
401 + 31501913 = 31502314
491 + 31501823 = 31502314
563 + 31501751 = 31502314

Showing the first eight; more decompositions exist.
