Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526006, here are decompositions:

79 + 31525927 = 31526006
97 + 31525909 = 31526006
103 + 31525903 = 31526006
157 + 31525849 = 31526006
223 + 31525783 = 31526006
229 + 31525777 = 31526006
283 + 31525723 = 31526006
307 + 31525699 = 31526006

Showing the first eight; more decompositions exist.
