Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 746, here are decompositions:

3 + 743 = 746
7 + 739 = 746
13 + 733 = 746
19 + 727 = 746
37 + 709 = 746
73 + 673 = 746
103 + 643 = 746
127 + 619 = 746

Showing the first eight; more decompositions exist.
