Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598548, here are decompositions:

5 + 31598543 = 31598548
11 + 31598537 = 31598548
29 + 31598519 = 31598548
89 + 31598459 = 31598548
131 + 31598417 = 31598548
167 + 31598381 = 31598548
227 + 31598321 = 31598548
269 + 31598279 = 31598548

Showing the first eight; more decompositions exist.
