Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517844, here are decompositions:

13 + 517831 = 517844
97 + 517747 = 517844
127 + 517717 = 517844
241 + 517603 = 517844
331 + 517513 = 517844
337 + 517507 = 517844
373 + 517471 = 517844
433 + 517411 = 517844

Showing the first eight; more decompositions exist.
