Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597602, here are decompositions:

31 + 31597571 = 31597602
53 + 31597549 = 31597602
61 + 31597541 = 31597602
109 + 31597493 = 31597602
131 + 31597471 = 31597602
149 + 31597453 = 31597602
191 + 31597411 = 31597602
349 + 31597253 = 31597602

Showing the first eight; more decompositions exist.
