Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567080, here are decompositions:

31 + 31567049 = 31567080
37 + 31567043 = 31567080
101 + 31566979 = 31567080
107 + 31566973 = 31567080
113 + 31566967 = 31567080
179 + 31566901 = 31567080
241 + 31566839 = 31567080
263 + 31566817 = 31567080

Showing the first eight; more decompositions exist.
