Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598574, here are decompositions:

31 + 31598543 = 31598574
37 + 31598537 = 31598574
53 + 31598521 = 31598574
61 + 31598513 = 31598574
151 + 31598423 = 31598574
157 + 31598417 = 31598574
173 + 31598401 = 31598574
193 + 31598381 = 31598574

Showing the first eight; more decompositions exist.
