Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77772, here are decompositions:

11 + 77761 = 77772
29 + 77743 = 77772
41 + 77731 = 77772
53 + 77719 = 77772
59 + 77713 = 77772
61 + 77711 = 77772
73 + 77699 = 77772
83 + 77689 = 77772

Showing the first eight; more decompositions exist.
