Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491548, here are decompositions:

11 + 491537 = 491548
17 + 491531 = 491548
47 + 491501 = 491548
59 + 491489 = 491548
131 + 491417 = 491548
191 + 491357 = 491548
251 + 491297 = 491548
269 + 491279 = 491548

Showing the first eight; more decompositions exist.
