Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493378, here are decompositions:

101 + 493277 = 493378
167 + 493211 = 493378
239 + 493139 = 493378
251 + 493127 = 493378
257 + 493121 = 493378
269 + 493109 = 493378
311 + 493067 = 493378
467 + 492911 = 493378

Showing the first eight; more decompositions exist.
