Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722236, here are decompositions:

13 + 8722223 = 8722236
43 + 8722193 = 8722236
67 + 8722169 = 8722236
113 + 8722123 = 8722236
137 + 8722099 = 8722236
139 + 8722097 = 8722236
157 + 8722079 = 8722236
227 + 8722009 = 8722236

Showing the first eight; more decompositions exist.
