Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712822, here are decompositions:

29 + 8712793 = 8712822
43 + 8712779 = 8712822
61 + 8712761 = 8712822
71 + 8712751 = 8712822
73 + 8712749 = 8712822
109 + 8712713 = 8712822
113 + 8712709 = 8712822
193 + 8712629 = 8712822

Showing the first eight; more decompositions exist.
