Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598500, here are decompositions:

41 + 31598459 = 31598500
83 + 31598417 = 31598500
137 + 31598363 = 31598500
173 + 31598327 = 31598500
179 + 31598321 = 31598500
233 + 31598267 = 31598500
239 + 31598261 = 31598500
359 + 31598141 = 31598500

Showing the first eight; more decompositions exist.
