Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463828, here are decompositions:

31 + 31463797 = 31463828
61 + 31463767 = 31463828
139 + 31463689 = 31463828
241 + 31463587 = 31463828
421 + 31463407 = 31463828
439 + 31463389 = 31463828
499 + 31463329 = 31463828
547 + 31463281 = 31463828

Showing the first eight; more decompositions exist.
