Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526286, here are decompositions:

5 + 31526281 = 31526286
13 + 31526273 = 31526286
47 + 31526239 = 31526286
59 + 31526227 = 31526286
73 + 31526213 = 31526286
79 + 31526207 = 31526286
89 + 31526197 = 31526286
97 + 31526189 = 31526286

Showing the first eight; more decompositions exist.
