Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502262, here are decompositions:

19 + 31502243 = 31502262
73 + 31502189 = 31502262
79 + 31502183 = 31502262
101 + 31502161 = 31502262
131 + 31502131 = 31502262
149 + 31502113 = 31502262
163 + 31502099 = 31502262
179 + 31502083 = 31502262

Showing the first eight; more decompositions exist.
