Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1676, here are decompositions:

7 + 1669 = 1676
13 + 1663 = 1676
19 + 1657 = 1676
67 + 1609 = 1676
79 + 1597 = 1676
97 + 1579 = 1676
109 + 1567 = 1676
127 + 1549 = 1676

Showing the first eight; more decompositions exist.
