Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491974, here are decompositions:

5 + 491969 = 491974
23 + 491951 = 491974
101 + 491873 = 491974
107 + 491867 = 491974
137 + 491837 = 491974
191 + 491783 = 491974
227 + 491747 = 491974
347 + 491627 = 491974

Showing the first eight; more decompositions exist.
