Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699878, here are decompositions:

71 + 8699807 = 8699878
107 + 8699771 = 8699878
311 + 8699567 = 8699878
359 + 8699519 = 8699878
389 + 8699489 = 8699878
491 + 8699387 = 8699878
569 + 8699309 = 8699878
599 + 8699279 = 8699878

Showing the first eight; more decompositions exist.
