Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526200, here are decompositions:

3 + 31526197 = 31526200
11 + 31526189 = 31526200
59 + 31526141 = 31526200
113 + 31526087 = 31526200
131 + 31526069 = 31526200
137 + 31526063 = 31526200
149 + 31526051 = 31526200
179 + 31526021 = 31526200

Showing the first eight; more decompositions exist.
