Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454074, here are decompositions:

83 + 31453991 = 31454074
131 + 31453943 = 31454074
191 + 31453883 = 31454074
233 + 31453841 = 31454074
251 + 31453823 = 31454074
347 + 31453727 = 31454074
503 + 31453571 = 31454074
647 + 31453427 = 31454074

Showing the first eight; more decompositions exist.
