Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504352, here are decompositions:

151 + 31504201 = 31504352
163 + 31504189 = 31504352
223 + 31504129 = 31504352
379 + 31503973 = 31504352
421 + 31503931 = 31504352
499 + 31503853 = 31504352
541 + 31503811 = 31504352
601 + 31503751 = 31504352

Showing the first eight; more decompositions exist.
