Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598182, here are decompositions:

3 + 31598179 = 31598182
41 + 31598141 = 31598182
149 + 31598033 = 31598182
173 + 31598009 = 31598182
269 + 31597913 = 31598182
359 + 31597823 = 31598182
389 + 31597793 = 31598182
419 + 31597763 = 31598182

Showing the first eight; more decompositions exist.
