Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491020, here are decompositions:

17 + 491003 = 491020
29 + 490991 = 491020
53 + 490967 = 491020
71 + 490949 = 491020
83 + 490937 = 491020
107 + 490913 = 491020
191 + 490829 = 491020
251 + 490769 = 491020

Showing the first eight; more decompositions exist.
