Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504270, here are decompositions:

41 + 31504229 = 31504270
137 + 31504133 = 31504270
167 + 31504103 = 31504270
173 + 31504097 = 31504270
233 + 31504037 = 31504270
257 + 31504013 = 31504270
293 + 31503977 = 31504270
353 + 31503917 = 31504270

Showing the first eight; more decompositions exist.
