Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495546, here are decompositions:

23 + 31495523 = 31495546
29 + 31495517 = 31495546
53 + 31495493 = 31495546
83 + 31495463 = 31495546
179 + 31495367 = 31495546
347 + 31495199 = 31495546
359 + 31495187 = 31495546
389 + 31495157 = 31495546

Showing the first eight; more decompositions exist.
