Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757222, here are decompositions:

13 + 8757209 = 8757222
31 + 8757191 = 8757222
43 + 8757179 = 8757222
79 + 8757143 = 8757222
101 + 8757121 = 8757222
109 + 8757113 = 8757222
113 + 8757109 = 8757222
139 + 8757083 = 8757222

Showing the first eight; more decompositions exist.
