Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491674, here are decompositions:

5 + 491669 = 491674
23 + 491651 = 491674
41 + 491633 = 491674
47 + 491627 = 491674
83 + 491591 = 491674
137 + 491537 = 491674
173 + 491501 = 491674
191 + 491483 = 491674

Showing the first eight; more decompositions exist.
