Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597436, here are decompositions:

19 + 31597417 = 31597436
193 + 31597243 = 31597436
223 + 31597213 = 31597436
307 + 31597129 = 31597436
337 + 31597099 = 31597436
433 + 31597003 = 31597436
439 + 31596997 = 31597436
487 + 31596949 = 31597436

Showing the first eight; more decompositions exist.
