Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491588, here are decompositions:

7 + 491581 = 491588
61 + 491527 = 491588
127 + 491461 = 491588
211 + 491377 = 491588
337 + 491251 = 491588
421 + 491167 = 491588
439 + 491149 = 491588
547 + 491041 = 491588

Showing the first eight; more decompositions exist.
