Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31032, here are decompositions:

13 + 31019 = 31032
19 + 31013 = 31032
61 + 30971 = 31032
83 + 30949 = 31032
101 + 30931 = 31032
139 + 30893 = 31032
151 + 30881 = 31032
163 + 30869 = 31032

Showing the first eight; more decompositions exist.
