Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491306, here are decompositions:

7 + 491299 = 491306
139 + 491167 = 491306
157 + 491149 = 491306
223 + 491083 = 491306
313 + 490993 = 491306
337 + 490969 = 491306
349 + 490957 = 491306
379 + 490927 = 491306

Showing the first eight; more decompositions exist.
