Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454194, here are decompositions:

3 + 31454191 = 31454194
47 + 31454147 = 31454194
71 + 31454123 = 31454194
113 + 31454081 = 31454194
197 + 31453997 = 31454194
251 + 31453943 = 31454194
263 + 31453931 = 31454194
311 + 31453883 = 31454194

Showing the first eight; more decompositions exist.
