Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452310, here are decompositions:

101 + 31452209 = 31452310
107 + 31452203 = 31452310
137 + 31452173 = 31452310
173 + 31452137 = 31452310
179 + 31452131 = 31452310
269 + 31452041 = 31452310
311 + 31451999 = 31452310
317 + 31451993 = 31452310

Showing the first eight; more decompositions exist.
