Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504356, here are decompositions:

5 + 31504351 = 31504356
29 + 31504327 = 31504356
53 + 31504303 = 31504356
127 + 31504229 = 31504356
137 + 31504219 = 31504356
167 + 31504189 = 31504356
173 + 31504183 = 31504356
223 + 31504133 = 31504356

Showing the first eight; more decompositions exist.
