Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491676, here are decompositions:

7 + 491669 = 491676
23 + 491653 = 491676
37 + 491639 = 491676
43 + 491633 = 491676
83 + 491593 = 491676
137 + 491539 = 491676
139 + 491537 = 491676
149 + 491527 = 491676

Showing the first eight; more decompositions exist.
