Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491852, here are decompositions:

19 + 491833 = 491852
79 + 491773 = 491852
199 + 491653 = 491852
241 + 491611 = 491852
271 + 491581 = 491852
313 + 491539 = 491852
349 + 491503 = 491852
499 + 491353 = 491852

Showing the first eight; more decompositions exist.
