Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18772, here are decompositions:

23 + 18749 = 18772
29 + 18743 = 18772
41 + 18731 = 18772
53 + 18719 = 18772
59 + 18713 = 18772
71 + 18701 = 18772
101 + 18671 = 18772
179 + 18593 = 18772

Showing the first eight; more decompositions exist.
