Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598404, here are decompositions:

3 + 31598401 = 31598404
23 + 31598381 = 31598404
41 + 31598363 = 31598404
83 + 31598321 = 31598404
137 + 31598267 = 31598404
191 + 31598213 = 31598404
263 + 31598141 = 31598404
347 + 31598057 = 31598404

Showing the first eight; more decompositions exist.
