Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456032, here are decompositions:

11 + 31456021 = 31456032
19 + 31456013 = 31456032
29 + 31456003 = 31456032
71 + 31455961 = 31456032
73 + 31455959 = 31456032
103 + 31455929 = 31456032
131 + 31455901 = 31456032
163 + 31455869 = 31456032

Showing the first eight; more decompositions exist.
