Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452150, here are decompositions:

13 + 31452137 = 31452150
19 + 31452131 = 31452150
29 + 31452121 = 31452150
53 + 31452097 = 31452150
61 + 31452089 = 31452150
71 + 31452079 = 31452150
89 + 31452061 = 31452150
109 + 31452041 = 31452150

Showing the first eight; more decompositions exist.
