Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18776, here are decompositions:

3 + 18773 = 18776
19 + 18757 = 18776
97 + 18679 = 18776
139 + 18637 = 18776
193 + 18583 = 18776
223 + 18553 = 18776
283 + 18493 = 18776
337 + 18439 = 18776

Showing the first eight; more decompositions exist.
