Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584060, here are decompositions:

17 + 31584043 = 31584060
41 + 31584019 = 31584060
61 + 31583999 = 31584060
71 + 31583989 = 31584060
89 + 31583971 = 31584060
139 + 31583921 = 31584060
149 + 31583911 = 31584060
163 + 31583897 = 31584060

Showing the first eight; more decompositions exist.
