Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502346, here are decompositions:

13 + 31502333 = 31502346
17 + 31502329 = 31502346
59 + 31502287 = 31502346
67 + 31502279 = 31502346
103 + 31502243 = 31502346
157 + 31502189 = 31502346
163 + 31502183 = 31502346
199 + 31502147 = 31502346

Showing the first eight; more decompositions exist.
