Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491696, here are decompositions:

19 + 491677 = 491696
43 + 491653 = 491696
103 + 491593 = 491696
157 + 491539 = 491696
193 + 491503 = 491696
199 + 491497 = 491696
367 + 491329 = 491696
397 + 491299 = 491696

Showing the first eight; more decompositions exist.
