Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491750, here are decompositions:

3 + 491747 = 491750
13 + 491737 = 491750
19 + 491731 = 491750
31 + 491719 = 491750
43 + 491707 = 491750
73 + 491677 = 491750
97 + 491653 = 491750
139 + 491611 = 491750

Showing the first eight; more decompositions exist.
