Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598184, here are decompositions:

5 + 31598179 = 31598184
41 + 31598143 = 31598184
43 + 31598141 = 31598184
47 + 31598137 = 31598184
83 + 31598101 = 31598184
127 + 31598057 = 31598184
151 + 31598033 = 31598184
157 + 31598027 = 31598184

Showing the first eight; more decompositions exist.
