Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8772, here are decompositions:

11 + 8761 = 8772
19 + 8753 = 8772
31 + 8741 = 8772
41 + 8731 = 8772
53 + 8719 = 8772
59 + 8713 = 8772
73 + 8699 = 8772
79 + 8693 = 8772

Showing the first eight; more decompositions exist.
