Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583066, here are decompositions:

19 + 31583047 = 31583066
43 + 31583023 = 31583066
337 + 31582729 = 31583066
433 + 31582633 = 31583066
439 + 31582627 = 31583066
457 + 31582609 = 31583066
577 + 31582489 = 31583066
733 + 31582333 = 31583066

Showing the first eight; more decompositions exist.
