Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583342, here are decompositions:

19 + 31583323 = 31583342
61 + 31583281 = 31583342
73 + 31583269 = 31583342
211 + 31583131 = 31583342
523 + 31582819 = 31583342
613 + 31582729 = 31583342
709 + 31582633 = 31583342
733 + 31582609 = 31583342

Showing the first eight; more decompositions exist.
