Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19772, here are decompositions:

13 + 19759 = 19772
19 + 19753 = 19772
73 + 19699 = 19772
163 + 19609 = 19772
229 + 19543 = 19772
241 + 19531 = 19772
271 + 19501 = 19772
283 + 19489 = 19772

Showing the first eight; more decompositions exist.
