Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598470, here are decompositions:

11 + 31598459 = 31598470
47 + 31598423 = 31598470
53 + 31598417 = 31598470
89 + 31598381 = 31598470
107 + 31598363 = 31598470
149 + 31598321 = 31598470
191 + 31598279 = 31598470
257 + 31598213 = 31598470

Showing the first eight; more decompositions exist.
