Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598912, here are decompositions:

3 + 31598909 = 31598912
73 + 31598839 = 31598912
211 + 31598701 = 31598912
229 + 31598683 = 31598912
463 + 31598449 = 31598912
613 + 31598299 = 31598912
673 + 31598239 = 31598912
733 + 31598179 = 31598912

Showing the first eight; more decompositions exist.
