Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188772, here are decompositions:

5 + 188767 = 188772
19 + 188753 = 188772
43 + 188729 = 188772
53 + 188719 = 188772
61 + 188711 = 188772
71 + 188701 = 188772
79 + 188693 = 188772
139 + 188633 = 188772

Showing the first eight; more decompositions exist.
