Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722230, here are decompositions:

7 + 8722223 = 8722230
19 + 8722211 = 8722230
37 + 8722193 = 8722230
43 + 8722187 = 8722230
59 + 8722171 = 8722230
61 + 8722169 = 8722230
107 + 8722123 = 8722230
113 + 8722117 = 8722230

Showing the first eight; more decompositions exist.
