Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453324, here are decompositions:

3 + 31453321 = 31453324
41 + 31453283 = 31453324
83 + 31453241 = 31453324
131 + 31453193 = 31453324
167 + 31453157 = 31453324
191 + 31453133 = 31453324
347 + 31452977 = 31453324
521 + 31452803 = 31453324

Showing the first eight; more decompositions exist.
