Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493418, here are decompositions:

19 + 493399 = 493418
67 + 493351 = 493418
127 + 493291 = 493418
139 + 493279 = 493418
199 + 493219 = 493418
241 + 493177 = 493418
271 + 493147 = 493418
307 + 493111 = 493418

Showing the first eight; more decompositions exist.
