Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583076, here are decompositions:

29 + 31583047 = 31583076
43 + 31583033 = 31583076
53 + 31583023 = 31583076
127 + 31582949 = 31583076
139 + 31582937 = 31583076
163 + 31582913 = 31583076
179 + 31582897 = 31583076
229 + 31582847 = 31583076

Showing the first eight; more decompositions exist.
