Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598530, here are decompositions:

11 + 31598519 = 31598530
17 + 31598513 = 31598530
71 + 31598459 = 31598530
107 + 31598423 = 31598530
113 + 31598417 = 31598530
149 + 31598381 = 31598530
167 + 31598363 = 31598530
251 + 31598279 = 31598530

Showing the first eight; more decompositions exist.
