Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526800, here are decompositions:

23 + 31526777 = 31526800
29 + 31526771 = 31526800
47 + 31526753 = 31526800
131 + 31526669 = 31526800
167 + 31526633 = 31526800
197 + 31526603 = 31526800
311 + 31526489 = 31526800
449 + 31526351 = 31526800

Showing the first eight; more decompositions exist.
