Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493918, here are decompositions:

41 + 493877 = 493918
59 + 493859 = 493918
101 + 493817 = 493918
107 + 493811 = 493918
197 + 493721 = 493918
311 + 493607 = 493918
461 + 493457 = 493918
521 + 493397 = 493918

Showing the first eight; more decompositions exist.
