Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599068, here are decompositions:

79 + 31598989 = 31599068
157 + 31598911 = 31599068
181 + 31598887 = 31599068
211 + 31598857 = 31599068
229 + 31598839 = 31599068
367 + 31598701 = 31599068
421 + 31598647 = 31599068
547 + 31598521 = 31599068

Showing the first eight; more decompositions exist.
