Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583576, here are decompositions:

67 + 31583509 = 31583576
127 + 31583449 = 31583576
139 + 31583437 = 31583576
163 + 31583413 = 31583576
223 + 31583353 = 31583576
307 + 31583269 = 31583576
439 + 31583137 = 31583576
757 + 31582819 = 31583576

Showing the first eight; more decompositions exist.
