Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598712, here are decompositions:

11 + 31598701 = 31598712
29 + 31598683 = 31598712
43 + 31598669 = 31598712
191 + 31598521 = 31598712
193 + 31598519 = 31598712
199 + 31598513 = 31598712
263 + 31598449 = 31598712
293 + 31598419 = 31598712

Showing the first eight; more decompositions exist.
