Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495936, here are decompositions:

89 + 31495847 = 31495936
179 + 31495757 = 31495936
347 + 31495589 = 31495936
419 + 31495517 = 31495936
443 + 31495493 = 31495936
467 + 31495469 = 31495936
569 + 31495367 = 31495936
827 + 31495109 = 31495936

Showing the first eight; more decompositions exist.
