Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491792, here are decompositions:

3 + 491789 = 491792
19 + 491773 = 491792
61 + 491731 = 491792
73 + 491719 = 491792
139 + 491653 = 491792
181 + 491611 = 491792
199 + 491593 = 491792
211 + 491581 = 491792

Showing the first eight; more decompositions exist.
