Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491976, here are decompositions:

7 + 491969 = 491976
53 + 491923 = 491976
103 + 491873 = 491976
109 + 491867 = 491976
139 + 491837 = 491976
157 + 491819 = 491976
179 + 491797 = 491976
193 + 491783 = 491976

Showing the first eight; more decompositions exist.
