Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534892, here are decompositions:

13 + 31534879 = 31534892
19 + 31534873 = 31534892
61 + 31534831 = 31534892
73 + 31534819 = 31534892
139 + 31534753 = 31534892
163 + 31534729 = 31534892
223 + 31534669 = 31534892
241 + 31534651 = 31534892

Showing the first eight; more decompositions exist.
