Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598556, here are decompositions:

13 + 31598543 = 31598556
19 + 31598537 = 31598556
37 + 31598519 = 31598556
43 + 31598513 = 31598556
97 + 31598459 = 31598556
107 + 31598449 = 31598556
137 + 31598419 = 31598556
139 + 31598417 = 31598556

Showing the first eight; more decompositions exist.
