Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452132, here are decompositions:

11 + 31452121 = 31452132
43 + 31452089 = 31452132
53 + 31452079 = 31452132
71 + 31452061 = 31452132
113 + 31452019 = 31452132
139 + 31451993 = 31452132
163 + 31451969 = 31452132
223 + 31451909 = 31452132

Showing the first eight; more decompositions exist.
