Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495452, here are decompositions:

5 + 31495447 = 31495452
29 + 31495423 = 31495452
101 + 31495351 = 31495452
179 + 31495273 = 31495452
211 + 31495241 = 31495452
239 + 31495213 = 31495452
281 + 31495171 = 31495452
389 + 31495063 = 31495452

Showing the first eight; more decompositions exist.
