Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567110, here are decompositions:

19 + 31567091 = 31567110
23 + 31567087 = 31567110
61 + 31567049 = 31567110
67 + 31567043 = 31567110
131 + 31566979 = 31567110
137 + 31566973 = 31567110
191 + 31566919 = 31567110
199 + 31566911 = 31567110

Showing the first eight; more decompositions exist.
