Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453272, here are decompositions:

5 + 31453267 = 31453272
23 + 31453249 = 31453272
31 + 31453241 = 31453272
79 + 31453193 = 31453272
101 + 31453171 = 31453272
113 + 31453159 = 31453272
131 + 31453141 = 31453272
139 + 31453133 = 31453272

Showing the first eight; more decompositions exist.
