Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452352, here are decompositions:

11 + 31452341 = 31452352
149 + 31452203 = 31452352
179 + 31452173 = 31452352
263 + 31452089 = 31452352
311 + 31452041 = 31452352
353 + 31451999 = 31452352
359 + 31451993 = 31452352
383 + 31451969 = 31452352

Showing the first eight; more decompositions exist.
