Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599194, here are decompositions:

37 + 31599157 = 31599194
241 + 31598953 = 31599194
271 + 31598923 = 31599194
283 + 31598911 = 31599194
307 + 31598887 = 31599194
331 + 31598863 = 31599194
337 + 31598857 = 31599194
547 + 31598647 = 31599194

Showing the first eight; more decompositions exist.
