Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534080, here are decompositions:

7 + 31534073 = 31534080
13 + 31534067 = 31534080
23 + 31534057 = 31534080
29 + 31534051 = 31534080
47 + 31534033 = 31534080
101 + 31533979 = 31534080
113 + 31533967 = 31534080
131 + 31533949 = 31534080

Showing the first eight; more decompositions exist.
