Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491410, here are decompositions:

53 + 491357 = 491410
71 + 491339 = 491410
83 + 491327 = 491410
113 + 491297 = 491410
131 + 491279 = 491410
137 + 491273 = 491410
149 + 491261 = 491410
191 + 491219 = 491410

Showing the first eight; more decompositions exist.
