Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567104, here are decompositions:

13 + 31567091 = 31567104
17 + 31567087 = 31567104
61 + 31567043 = 31567104
131 + 31566973 = 31567104
137 + 31566967 = 31567104
193 + 31566911 = 31567104
241 + 31566863 = 31567104
277 + 31566827 = 31567104

Showing the first eight; more decompositions exist.
