Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495852, here are decompositions:

5 + 31495847 = 31495852
191 + 31495661 = 31495852
251 + 31495601 = 31495852
263 + 31495589 = 31495852
359 + 31495493 = 31495852
383 + 31495469 = 31495852
389 + 31495463 = 31495852
449 + 31495403 = 31495852

Showing the first eight; more decompositions exist.
