Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491276, here are decompositions:

3 + 491273 = 491276
109 + 491167 = 491276
127 + 491149 = 491276
139 + 491137 = 491276
193 + 491083 = 491276
283 + 490993 = 491276
307 + 490969 = 491276
349 + 490927 = 491276

Showing the first eight; more decompositions exist.
