Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467834, here are decompositions:

5 + 31467829 = 31467834
23 + 31467811 = 31467834
67 + 31467767 = 31467834
71 + 31467763 = 31467834
107 + 31467727 = 31467834
113 + 31467721 = 31467834
157 + 31467677 = 31467834
241 + 31467593 = 31467834

Showing the first eight; more decompositions exist.
