Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567026, here are decompositions:

47 + 31566979 = 31567026
53 + 31566973 = 31567026
59 + 31566967 = 31567026
107 + 31566919 = 31567026
163 + 31566863 = 31567026
199 + 31566827 = 31567026
223 + 31566803 = 31567026
229 + 31566797 = 31567026

Showing the first eight; more decompositions exist.
