Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718372, here are decompositions:

23 + 8718349 = 8718372
29 + 8718343 = 8718372
59 + 8718313 = 8718372
71 + 8718301 = 8718372
101 + 8718271 = 8718372
151 + 8718221 = 8718372
181 + 8718191 = 8718372
263 + 8718109 = 8718372

Showing the first eight; more decompositions exist.
