Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493740, here are decompositions:

7 + 493733 = 493740
11 + 493729 = 493740
19 + 493721 = 493740
29 + 493711 = 493740
31 + 493709 = 493740
47 + 493693 = 493740
83 + 493657 = 493740
97 + 493643 = 493740

Showing the first eight; more decompositions exist.
