Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491318, here are decompositions:

19 + 491299 = 491318
67 + 491251 = 491318
151 + 491167 = 491318
181 + 491137 = 491318
277 + 491041 = 491318
349 + 490969 = 491318
367 + 490951 = 491318
397 + 490921 = 491318

Showing the first eight; more decompositions exist.
