Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19746, here are decompositions:

7 + 19739 = 19746
19 + 19727 = 19746
29 + 19717 = 19746
37 + 19709 = 19746
47 + 19699 = 19746
59 + 19687 = 19746
137 + 19609 = 19746
149 + 19597 = 19746

Showing the first eight; more decompositions exist.
