Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718922, here are decompositions:

5 + 8718917 = 8718922
41 + 8718881 = 8718922
53 + 8718869 = 8718922
71 + 8718851 = 8718922
83 + 8718839 = 8718922
89 + 8718833 = 8718922
383 + 8718539 = 8718922
419 + 8718503 = 8718922

Showing the first eight; more decompositions exist.
