Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598342, here are decompositions:

43 + 31598299 = 31598342
103 + 31598239 = 31598342
151 + 31598191 = 31598342
163 + 31598179 = 31598342
199 + 31598143 = 31598342
241 + 31598101 = 31598342
313 + 31598029 = 31598342
331 + 31598011 = 31598342

Showing the first eight; more decompositions exist.
