Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597190, here are decompositions:

13 + 31597177 = 31597190
61 + 31597129 = 31597190
109 + 31597081 = 31597190
139 + 31597051 = 31597190
193 + 31596997 = 31597190
199 + 31596991 = 31597190
241 + 31596949 = 31597190
277 + 31596913 = 31597190

Showing the first eight; more decompositions exist.
