Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598338, here are decompositions:

11 + 31598327 = 31598338
17 + 31598321 = 31598338
59 + 31598279 = 31598338
71 + 31598267 = 31598338
137 + 31598201 = 31598338
197 + 31598141 = 31598338
281 + 31598057 = 31598338
311 + 31598027 = 31598338

Showing the first eight; more decompositions exist.
