Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454098, here are decompositions:

17 + 31454081 = 31454098
101 + 31453997 = 31454098
107 + 31453991 = 31454098
167 + 31453931 = 31454098
257 + 31453841 = 31454098
419 + 31453679 = 31454098
521 + 31453577 = 31454098
569 + 31453529 = 31454098

Showing the first eight; more decompositions exist.
