Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534926, here are decompositions:

13 + 31534913 = 31534926
47 + 31534879 = 31534926
53 + 31534873 = 31534926
107 + 31534819 = 31534926
127 + 31534799 = 31534926
139 + 31534787 = 31534926
173 + 31534753 = 31534926
197 + 31534729 = 31534926

Showing the first eight; more decompositions exist.
