Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186772, here are decompositions:

11 + 186761 = 186772
29 + 186743 = 186772
71 + 186701 = 186772
83 + 186689 = 186772
101 + 186671 = 186772
191 + 186581 = 186772
293 + 186479 = 186772
353 + 186419 = 186772

Showing the first eight; more decompositions exist.
