Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452162, here are decompositions:

31 + 31452131 = 31452162
41 + 31452121 = 31452162
73 + 31452089 = 31452162
83 + 31452079 = 31452162
101 + 31452061 = 31452162
149 + 31452013 = 31452162
163 + 31451999 = 31452162
193 + 31451969 = 31452162

Showing the first eight; more decompositions exist.
