Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452108, here are decompositions:

11 + 31452097 = 31452108
19 + 31452089 = 31452108
29 + 31452079 = 31452108
47 + 31452061 = 31452108
67 + 31452041 = 31452108
89 + 31452019 = 31452108
101 + 31452007 = 31452108
109 + 31451999 = 31452108

Showing the first eight; more decompositions exist.
