Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583006, here are decompositions:

109 + 31582897 = 31583006
229 + 31582777 = 31583006
277 + 31582729 = 31583006
373 + 31582633 = 31583006
379 + 31582627 = 31583006
397 + 31582609 = 31583006
607 + 31582399 = 31583006
673 + 31582333 = 31583006

Showing the first eight; more decompositions exist.
