Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598286, here are decompositions:

7 + 31598279 = 31598286
19 + 31598267 = 31598286
47 + 31598239 = 31598286
59 + 31598227 = 31598286
73 + 31598213 = 31598286
107 + 31598179 = 31598286
149 + 31598137 = 31598286
229 + 31598057 = 31598286

Showing the first eight; more decompositions exist.
