Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526180, here are decompositions:

97 + 31526083 = 31526180
199 + 31525981 = 31526180
223 + 31525957 = 31526180
229 + 31525951 = 31526180
271 + 31525909 = 31526180
277 + 31525903 = 31526180
331 + 31525849 = 31526180
397 + 31525783 = 31526180

Showing the first eight; more decompositions exist.
