Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491968, here are decompositions:

17 + 491951 = 491968
101 + 491867 = 491968
131 + 491837 = 491968
149 + 491819 = 491968
179 + 491789 = 491968
317 + 491651 = 491968
431 + 491537 = 491968
467 + 491501 = 491968

Showing the first eight; more decompositions exist.
