Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598598, here are decompositions:

7 + 31598591 = 31598598
61 + 31598537 = 31598598
79 + 31598519 = 31598598
139 + 31598459 = 31598598
149 + 31598449 = 31598598
179 + 31598419 = 31598598
181 + 31598417 = 31598598
197 + 31598401 = 31598598

Showing the first eight; more decompositions exist.
