Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454110, here are decompositions:

29 + 31454081 = 31454110
113 + 31453997 = 31454110
167 + 31453943 = 31454110
179 + 31453931 = 31454110
227 + 31453883 = 31454110
269 + 31453841 = 31454110
383 + 31453727 = 31454110
431 + 31453679 = 31454110

Showing the first eight; more decompositions exist.
