Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452246, here are decompositions:

5 + 31452241 = 31452246
13 + 31452233 = 31452246
37 + 31452209 = 31452246
43 + 31452203 = 31452246
47 + 31452199 = 31452246
73 + 31452173 = 31452246
109 + 31452137 = 31452246
149 + 31452097 = 31452246

Showing the first eight; more decompositions exist.
