Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597452, here are decompositions:

41 + 31597411 = 31597452
191 + 31597261 = 31597452
199 + 31597253 = 31597452
239 + 31597213 = 31597452
331 + 31597121 = 31597452
353 + 31597099 = 31597452
401 + 31597051 = 31597452
409 + 31597043 = 31597452

Showing the first eight; more decompositions exist.
