Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567206, here are decompositions:

53 + 31567153 = 31567206
157 + 31567049 = 31567206
163 + 31567043 = 31567206
227 + 31566979 = 31567206
233 + 31566973 = 31567206
239 + 31566967 = 31567206
367 + 31566839 = 31567206
379 + 31566827 = 31567206

Showing the first eight; more decompositions exist.
