Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598236, here are decompositions:

23 + 31598213 = 31598236
179 + 31598057 = 31598236
227 + 31598009 = 31598236
239 + 31597997 = 31598236
359 + 31597877 = 31598236
443 + 31597793 = 31598236
563 + 31597673 = 31598236
743 + 31597493 = 31598236

Showing the first eight; more decompositions exist.
