Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491876, here are decompositions:

3 + 491873 = 491876
19 + 491857 = 491876
43 + 491833 = 491876
79 + 491797 = 491876
103 + 491773 = 491876
139 + 491737 = 491876
157 + 491719 = 491876
199 + 491677 = 491876

Showing the first eight; more decompositions exist.
