Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585298, here are decompositions:

37 + 31585261 = 31585298
109 + 31585189 = 31585298
127 + 31585171 = 31585298
139 + 31585159 = 31585298
331 + 31584967 = 31585298
337 + 31584961 = 31585298
397 + 31584901 = 31585298
541 + 31584757 = 31585298

Showing the first eight; more decompositions exist.
