Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452024, here are decompositions:

5 + 31452019 = 31452024
11 + 31452013 = 31452024
17 + 31452007 = 31452024
31 + 31451993 = 31452024
167 + 31451857 = 31452024
223 + 31451801 = 31452024
271 + 31451753 = 31452024
293 + 31451731 = 31452024

Showing the first eight; more decompositions exist.
