Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493436, here are decompositions:

3 + 493433 = 493436
37 + 493399 = 493436
43 + 493393 = 493436
67 + 493369 = 493436
103 + 493333 = 493436
157 + 493279 = 493436
193 + 493243 = 493436
277 + 493159 = 493436

Showing the first eight; more decompositions exist.
