Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495410, here are decompositions:

7 + 31495403 = 31495410
43 + 31495367 = 31495410
53 + 31495357 = 31495410
59 + 31495351 = 31495410
137 + 31495273 = 31495410
197 + 31495213 = 31495410
211 + 31495199 = 31495410
223 + 31495187 = 31495410

Showing the first eight; more decompositions exist.
