Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598810, here are decompositions:

31 + 31598779 = 31598810
109 + 31598701 = 31598810
127 + 31598683 = 31598810
163 + 31598647 = 31598810
409 + 31598401 = 31598810
433 + 31598377 = 31598810
457 + 31598353 = 31598810
571 + 31598239 = 31598810

Showing the first eight; more decompositions exist.
