Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532926, here are decompositions:

3 + 31532923 = 31532926
53 + 31532873 = 31532926
59 + 31532867 = 31532926
149 + 31532777 = 31532926
233 + 31532693 = 31532926
239 + 31532687 = 31532926
353 + 31532573 = 31532926
419 + 31532507 = 31532926

Showing the first eight; more decompositions exist.
