Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545822, here are decompositions:

31 + 545791 = 545822
73 + 545749 = 545822
181 + 545641 = 545822
223 + 545599 = 545822
271 + 545551 = 545822
349 + 545473 = 545822
373 + 545449 = 545822
379 + 545443 = 545822

Showing the first eight; more decompositions exist.
