Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452248, here are decompositions:

7 + 31452241 = 31452248
67 + 31452181 = 31452248
127 + 31452121 = 31452248
151 + 31452097 = 31452248
229 + 31452019 = 31452248
241 + 31452007 = 31452248
367 + 31451881 = 31452248
379 + 31451869 = 31452248

Showing the first eight; more decompositions exist.
