Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1708, here are decompositions:

11 + 1697 = 1708
41 + 1667 = 1708
71 + 1637 = 1708
89 + 1619 = 1708
101 + 1607 = 1708
107 + 1601 = 1708
137 + 1571 = 1708
149 + 1559 = 1708

Showing the first eight; more decompositions exist.
