Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598252, here are decompositions:

13 + 31598239 = 31598252
61 + 31598191 = 31598252
73 + 31598179 = 31598252
109 + 31598143 = 31598252
151 + 31598101 = 31598252
223 + 31598029 = 31598252
241 + 31598011 = 31598252
373 + 31597879 = 31598252

Showing the first eight; more decompositions exist.
