Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583616, here are decompositions:

19 + 31583597 = 31583616
67 + 31583549 = 31583616
89 + 31583527 = 31583616
107 + 31583509 = 31583616
109 + 31583507 = 31583616
139 + 31583477 = 31583616
167 + 31583449 = 31583616
179 + 31583437 = 31583616

Showing the first eight; more decompositions exist.
