Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491156, here are decompositions:

7 + 491149 = 491156
19 + 491137 = 491156
73 + 491083 = 491156
97 + 491059 = 491156
163 + 490993 = 491156
199 + 490957 = 491156
229 + 490927 = 491156
307 + 490849 = 491156

Showing the first eight; more decompositions exist.
