Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453206, here are decompositions:

13 + 31453193 = 31453206
47 + 31453159 = 31453206
73 + 31453133 = 31453206
167 + 31453039 = 31453206
229 + 31452977 = 31453206
233 + 31452973 = 31453206
263 + 31452943 = 31453206
347 + 31452859 = 31453206

Showing the first eight; more decompositions exist.
