Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599748, here are decompositions:

41 + 31599707 = 31599748
137 + 31599611 = 31599748
149 + 31599599 = 31599748
197 + 31599551 = 31599748
317 + 31599431 = 31599748
359 + 31599389 = 31599748
647 + 31599101 = 31599748
809 + 31598939 = 31599748

Showing the first eight; more decompositions exist.
