Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495926, here are decompositions:

5 + 31495921 = 31495926
29 + 31495897 = 31495926
47 + 31495879 = 31495926
67 + 31495859 = 31495926
79 + 31495847 = 31495926
107 + 31495819 = 31495926
173 + 31495753 = 31495926
193 + 31495733 = 31495926

Showing the first eight; more decompositions exist.
