Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491796, here are decompositions:

7 + 491789 = 491796
13 + 491783 = 491796
23 + 491773 = 491796
59 + 491737 = 491796
89 + 491707 = 491796
127 + 491669 = 491796
157 + 491639 = 491796
163 + 491633 = 491796

Showing the first eight; more decompositions exist.
