Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504234, here are decompositions:

5 + 31504229 = 31504234
101 + 31504133 = 31504234
107 + 31504127 = 31504234
131 + 31504103 = 31504234
137 + 31504097 = 31504234
197 + 31504037 = 31504234
257 + 31503977 = 31504234
263 + 31503971 = 31504234

Showing the first eight; more decompositions exist.
