Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491458, here are decompositions:

29 + 491429 = 491458
41 + 491417 = 491458
101 + 491357 = 491458
131 + 491327 = 491458
179 + 491279 = 491458
197 + 491261 = 491458
239 + 491219 = 491458
257 + 491201 = 491458

Showing the first eight; more decompositions exist.
