Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491670, here are decompositions:

17 + 491653 = 491670
19 + 491651 = 491670
31 + 491639 = 491670
37 + 491633 = 491670
43 + 491627 = 491670
59 + 491611 = 491670
79 + 491591 = 491670
89 + 491581 = 491670

Showing the first eight; more decompositions exist.
