Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597574, here are decompositions:

3 + 31597571 = 31597574
67 + 31597507 = 31597574
103 + 31597471 = 31597574
157 + 31597417 = 31597574
163 + 31597411 = 31597574
313 + 31597261 = 31597574
331 + 31597243 = 31597574
397 + 31597177 = 31597574

Showing the first eight; more decompositions exist.
