Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583160, here are decompositions:

13 + 31583147 = 31583160
23 + 31583137 = 31583160
29 + 31583131 = 31583160
73 + 31583087 = 31583160
79 + 31583081 = 31583160
109 + 31583051 = 31583160
113 + 31583047 = 31583160
127 + 31583033 = 31583160

Showing the first eight; more decompositions exist.
