Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534836, here are decompositions:

5 + 31534831 = 31534836
17 + 31534819 = 31534836
37 + 31534799 = 31534836
79 + 31534757 = 31534836
83 + 31534753 = 31534836
97 + 31534739 = 31534836
107 + 31534729 = 31534836
127 + 31534709 = 31534836

Showing the first eight; more decompositions exist.
