Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504204, here are decompositions:

3 + 31504201 = 31504204
71 + 31504133 = 31504204
101 + 31504103 = 31504204
107 + 31504097 = 31504204
167 + 31504037 = 31504204
191 + 31504013 = 31504204
227 + 31503977 = 31504204
233 + 31503971 = 31504204

Showing the first eight; more decompositions exist.
