Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598194, here are decompositions:

3 + 31598191 = 31598194
53 + 31598141 = 31598194
137 + 31598057 = 31598194
167 + 31598027 = 31598194
197 + 31597997 = 31598194
233 + 31597961 = 31598194
281 + 31597913 = 31598194
317 + 31597877 = 31598194

Showing the first eight; more decompositions exist.
