Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491774, here are decompositions:

37 + 491737 = 491774
43 + 491731 = 491774
67 + 491707 = 491774
97 + 491677 = 491774
163 + 491611 = 491774
181 + 491593 = 491774
193 + 491581 = 491774
271 + 491503 = 491774

Showing the first eight; more decompositions exist.
