Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452358, here are decompositions:

17 + 31452341 = 31452358
149 + 31452209 = 31452358
227 + 31452131 = 31452358
269 + 31452089 = 31452358
317 + 31452041 = 31452358
359 + 31451999 = 31452358
389 + 31451969 = 31452358
449 + 31451909 = 31452358

Showing the first eight; more decompositions exist.
