Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493258, here are decompositions:

41 + 493217 = 493258
47 + 493211 = 493258
89 + 493169 = 493258
131 + 493127 = 493258
137 + 493121 = 493258
149 + 493109 = 493258
191 + 493067 = 493258
257 + 493001 = 493258

Showing the first eight; more decompositions exist.
