Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491088, here are decompositions:

5 + 491083 = 491088
7 + 491081 = 491088
29 + 491059 = 491088
47 + 491041 = 491088
97 + 490991 = 491088
131 + 490957 = 491088
137 + 490951 = 491088
139 + 490949 = 491088

Showing the first eight; more decompositions exist.
