Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598244, here are decompositions:

5 + 31598239 = 31598244
17 + 31598227 = 31598244
31 + 31598213 = 31598244
43 + 31598201 = 31598244
53 + 31598191 = 31598244
101 + 31598143 = 31598244
103 + 31598141 = 31598244
107 + 31598137 = 31598244

Showing the first eight; more decompositions exist.
