Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493238, here are decompositions:

7 + 493231 = 493238
19 + 493219 = 493238
37 + 493201 = 493238
61 + 493177 = 493238
79 + 493159 = 493238
127 + 493111 = 493238
211 + 493027 = 493238
271 + 492967 = 493238

Showing the first eight; more decompositions exist.
