Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454092, here are decompositions:

11 + 31454081 = 31454092
101 + 31453991 = 31454092
149 + 31453943 = 31454092
251 + 31453841 = 31454092
269 + 31453823 = 31454092
359 + 31453733 = 31454092
521 + 31453571 = 31454092
563 + 31453529 = 31454092

Showing the first eight; more decompositions exist.
