Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452126, here are decompositions:

5 + 31452121 = 31452126
29 + 31452097 = 31452126
37 + 31452089 = 31452126
47 + 31452079 = 31452126
107 + 31452019 = 31452126
113 + 31452013 = 31452126
127 + 31451999 = 31452126
157 + 31451969 = 31452126

Showing the first eight; more decompositions exist.
