Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583372, here are decompositions:

19 + 31583353 = 31583372
103 + 31583269 = 31583372
241 + 31583131 = 31583372
349 + 31583023 = 31583372
421 + 31582951 = 31583372
643 + 31582729 = 31583372
739 + 31582633 = 31583372
859 + 31582513 = 31583372

Showing the first eight; more decompositions exist.
