Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583116, here are decompositions:

29 + 31583087 = 31583116
83 + 31583033 = 31583116
167 + 31582949 = 31583116
179 + 31582937 = 31583116
269 + 31582847 = 31583116
293 + 31582823 = 31583116
359 + 31582757 = 31583116
443 + 31582673 = 31583116

Showing the first eight; more decompositions exist.
