Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722136, here are decompositions:

13 + 8722123 = 8722136
19 + 8722117 = 8722136
37 + 8722099 = 8722136
43 + 8722093 = 8722136
103 + 8722033 = 8722136
109 + 8722027 = 8722136
127 + 8722009 = 8722136
139 + 8721997 = 8722136

Showing the first eight; more decompositions exist.
