Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452176, here are decompositions:

3 + 31452173 = 31452176
79 + 31452097 = 31452176
97 + 31452079 = 31452176
157 + 31452019 = 31452176
163 + 31452013 = 31452176
307 + 31451869 = 31452176
337 + 31451839 = 31452176
463 + 31451713 = 31452176

Showing the first eight; more decompositions exist.
