Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533862, here are decompositions:

23 + 31533839 = 31533862
29 + 31533833 = 31533862
71 + 31533791 = 31533862
89 + 31533773 = 31533862
251 + 31533611 = 31533862
263 + 31533599 = 31533862
281 + 31533581 = 31533862
401 + 31533461 = 31533862

Showing the first eight; more decompositions exist.
