Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583000, here are decompositions:

19 + 31582981 = 31583000
103 + 31582897 = 31583000
109 + 31582891 = 31583000
181 + 31582819 = 31583000
223 + 31582777 = 31583000
271 + 31582729 = 31583000
367 + 31582633 = 31583000
373 + 31582627 = 31583000

Showing the first eight; more decompositions exist.
