Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598526, here are decompositions:

5 + 31598521 = 31598526
7 + 31598519 = 31598526
13 + 31598513 = 31598526
67 + 31598459 = 31598526
103 + 31598423 = 31598526
107 + 31598419 = 31598526
109 + 31598417 = 31598526
149 + 31598377 = 31598526

Showing the first eight; more decompositions exist.
