Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718826, here are decompositions:

3 + 8718823 = 8718826
23 + 8718803 = 8718826
29 + 8718797 = 8718826
47 + 8718779 = 8718826
89 + 8718737 = 8718826
419 + 8718407 = 8718826
449 + 8718377 = 8718826
827 + 8717999 = 8718826

Showing the first eight; more decompositions exist.
