Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567092, here are decompositions:

5 + 31567087 = 31567092
43 + 31567049 = 31567092
113 + 31566979 = 31567092
173 + 31566919 = 31567092
181 + 31566911 = 31567092
191 + 31566901 = 31567092
229 + 31566863 = 31567092
379 + 31566713 = 31567092

Showing the first eight; more decompositions exist.
