Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491098, here are decompositions:

17 + 491081 = 491098
59 + 491039 = 491098
107 + 490991 = 491098
131 + 490967 = 491098
149 + 490949 = 491098
239 + 490859 = 491098
269 + 490829 = 491098
401 + 490697 = 491098

Showing the first eight; more decompositions exist.
