Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526500, here are decompositions:

3 + 31526497 = 31526500
11 + 31526489 = 31526500
23 + 31526477 = 31526500
113 + 31526387 = 31526500
149 + 31526351 = 31526500
227 + 31526273 = 31526500
293 + 31526207 = 31526500
311 + 31526189 = 31526500

Showing the first eight; more decompositions exist.
