Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495404, here are decompositions:

37 + 31495367 = 31495404
43 + 31495361 = 31495404
47 + 31495357 = 31495404
53 + 31495351 = 31495404
71 + 31495333 = 31495404
131 + 31495273 = 31495404
163 + 31495241 = 31495404
191 + 31495213 = 31495404

Showing the first eight; more decompositions exist.
