Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453350, here are decompositions:

17 + 31453333 = 31453350
29 + 31453321 = 31453350
67 + 31453283 = 31453350
83 + 31453267 = 31453350
101 + 31453249 = 31453350
109 + 31453241 = 31453350
157 + 31453193 = 31453350
179 + 31453171 = 31453350

Showing the first eight; more decompositions exist.
