Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31088, here are decompositions:

7 + 31081 = 31088
19 + 31069 = 31088
37 + 31051 = 31088
139 + 30949 = 31088
151 + 30937 = 31088
157 + 30931 = 31088
229 + 30859 = 31088
271 + 30817 = 31088

Showing the first eight; more decompositions exist.
