Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452484, here are decompositions:

3 + 31452481 = 31452484
23 + 31452461 = 31452484
83 + 31452401 = 31452484
251 + 31452233 = 31452484
281 + 31452203 = 31452484
311 + 31452173 = 31452484
347 + 31452137 = 31452484
353 + 31452131 = 31452484

Showing the first eight; more decompositions exist.
