Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452022, here are decompositions:

3 + 31452019 = 31452022
23 + 31451999 = 31452022
29 + 31451993 = 31452022
53 + 31451969 = 31452022
113 + 31451909 = 31452022
269 + 31451753 = 31452022
293 + 31451729 = 31452022
311 + 31451711 = 31452022

Showing the first eight; more decompositions exist.
