Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 696, here are decompositions:

5 + 691 = 696
13 + 683 = 696
19 + 677 = 696
23 + 673 = 696
37 + 659 = 696
43 + 653 = 696
53 + 643 = 696
79 + 617 = 696

Showing the first eight; more decompositions exist.
