Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546836, here are decompositions:

5 + 31546831 = 31546836
19 + 31546817 = 31546836
23 + 31546813 = 31546836
29 + 31546807 = 31546836
37 + 31546799 = 31546836
47 + 31546789 = 31546836
127 + 31546709 = 31546836
173 + 31546663 = 31546836

Showing the first eight; more decompositions exist.
