Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598650, here are decompositions:

3 + 31598647 = 31598650
59 + 31598591 = 31598650
107 + 31598543 = 31598650
113 + 31598537 = 31598650
131 + 31598519 = 31598650
137 + 31598513 = 31598650
191 + 31598459 = 31598650
227 + 31598423 = 31598650

Showing the first eight; more decompositions exist.
