Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467394, here are decompositions:

5 + 31467389 = 31467394
47 + 31467347 = 31467394
83 + 31467311 = 31467394
191 + 31467203 = 31467394
227 + 31467167 = 31467394
311 + 31467083 = 31467394
383 + 31467011 = 31467394
401 + 31466993 = 31467394

Showing the first eight; more decompositions exist.
