Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511934, here are decompositions:

7 + 31511927 = 31511934
17 + 31511917 = 31511934
43 + 31511891 = 31511934
53 + 31511881 = 31511934
61 + 31511873 = 31511934
67 + 31511867 = 31511934
131 + 31511803 = 31511934
191 + 31511743 = 31511934

Showing the first eight; more decompositions exist.
