Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452092, here are decompositions:

3 + 31452089 = 31452092
13 + 31452079 = 31452092
31 + 31452061 = 31452092
73 + 31452019 = 31452092
79 + 31452013 = 31452092
163 + 31451929 = 31452092
211 + 31451881 = 31452092
223 + 31451869 = 31452092

Showing the first eight; more decompositions exist.
