Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491298, here are decompositions:

19 + 491279 = 491298
37 + 491261 = 491298
47 + 491251 = 491298
79 + 491219 = 491298
97 + 491201 = 491298
127 + 491171 = 491298
131 + 491167 = 491298
139 + 491159 = 491298

Showing the first eight; more decompositions exist.
