Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491706, here are decompositions:

29 + 491677 = 491706
37 + 491669 = 491706
53 + 491653 = 491706
67 + 491639 = 491706
73 + 491633 = 491706
79 + 491627 = 491706
113 + 491593 = 491706
167 + 491539 = 491706

Showing the first eight; more decompositions exist.
