Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454122, here are decompositions:

5 + 31454117 = 31454122
41 + 31454081 = 31454122
131 + 31453991 = 31454122
179 + 31453943 = 31454122
191 + 31453931 = 31454122
239 + 31453883 = 31454122
281 + 31453841 = 31454122
389 + 31453733 = 31454122

Showing the first eight; more decompositions exist.
