Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11772, here are decompositions:

29 + 11743 = 11772
41 + 11731 = 11772
53 + 11719 = 11772
71 + 11701 = 11772
73 + 11699 = 11772
83 + 11689 = 11772
139 + 11633 = 11772
151 + 11621 = 11772

Showing the first eight; more decompositions exist.
