Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598322, here are decompositions:

23 + 31598299 = 31598322
43 + 31598279 = 31598322
61 + 31598261 = 31598322
83 + 31598239 = 31598322
109 + 31598213 = 31598322
131 + 31598191 = 31598322
179 + 31598143 = 31598322
181 + 31598141 = 31598322

Showing the first eight; more decompositions exist.
