Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598254, here are decompositions:

41 + 31598213 = 31598254
53 + 31598201 = 31598254
113 + 31598141 = 31598254
197 + 31598057 = 31598254
227 + 31598027 = 31598254
257 + 31597997 = 31598254
293 + 31597961 = 31598254
431 + 31597823 = 31598254

Showing the first eight; more decompositions exist.
