Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454898, here are decompositions:

17 + 31454881 = 31454898
31 + 31454867 = 31454898
61 + 31454837 = 31454898
71 + 31454827 = 31454898
89 + 31454809 = 31454898
157 + 31454741 = 31454898
197 + 31454701 = 31454898
229 + 31454669 = 31454898

Showing the first eight; more decompositions exist.
