Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597088, here are decompositions:

7 + 31597081 = 31597088
37 + 31597051 = 31597088
97 + 31596991 = 31597088
139 + 31596949 = 31597088
181 + 31596907 = 31597088
199 + 31596889 = 31597088
241 + 31596847 = 31597088
331 + 31596757 = 31597088

Showing the first eight; more decompositions exist.
