Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723370, here are decompositions:

11 + 8723359 = 8723370
17 + 8723353 = 8723370
23 + 8723347 = 8723370
53 + 8723317 = 8723370
59 + 8723311 = 8723370
67 + 8723303 = 8723370
127 + 8723243 = 8723370
157 + 8723213 = 8723370

Showing the first eight; more decompositions exist.
