Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744160, here are decompositions:

11 + 8744149 = 8744160
17 + 8744143 = 8744160
31 + 8744129 = 8744160
59 + 8744101 = 8744160
79 + 8744081 = 8744160
97 + 8744063 = 8744160
127 + 8744033 = 8744160
137 + 8744023 = 8744160

Showing the first eight; more decompositions exist.
