Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534208, here are decompositions:

67 + 31534141 = 31534208
151 + 31534057 = 31534208
157 + 31534051 = 31534208
229 + 31533979 = 31534208
241 + 31533967 = 31534208
337 + 31533871 = 31534208
379 + 31533829 = 31534208
439 + 31533769 = 31534208

Showing the first eight; more decompositions exist.
