Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597392, here are decompositions:

109 + 31597283 = 31597392
131 + 31597261 = 31597392
139 + 31597253 = 31597392
149 + 31597243 = 31597392
179 + 31597213 = 31597392
193 + 31597199 = 31597392
241 + 31597151 = 31597392
263 + 31597129 = 31597392

Showing the first eight; more decompositions exist.
