Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526240, here are decompositions:

13 + 31526227 = 31526240
19 + 31526221 = 31526240
43 + 31526197 = 31526240
157 + 31526083 = 31526240
283 + 31525957 = 31526240
313 + 31525927 = 31526240
331 + 31525909 = 31526240
337 + 31525903 = 31526240

Showing the first eight; more decompositions exist.
