Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526868, here are decompositions:

5 + 31526863 = 31526868
59 + 31526809 = 31526868
97 + 31526771 = 31526868
137 + 31526731 = 31526868
179 + 31526689 = 31526868
199 + 31526669 = 31526868
251 + 31526617 = 31526868
379 + 31526489 = 31526868

Showing the first eight; more decompositions exist.
