Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491926, here are decompositions:

3 + 491923 = 491926
53 + 491873 = 491926
59 + 491867 = 491926
89 + 491837 = 491926
107 + 491819 = 491926
137 + 491789 = 491926
179 + 491747 = 491926
257 + 491669 = 491926

Showing the first eight; more decompositions exist.
