Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504174, here are decompositions:

41 + 31504133 = 31504174
47 + 31504127 = 31504174
71 + 31504103 = 31504174
137 + 31504037 = 31504174
197 + 31503977 = 31504174
257 + 31503917 = 31504174
263 + 31503911 = 31504174
311 + 31503863 = 31504174

Showing the first eight; more decompositions exist.
