Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986644, here are decompositions:

3 + 986641 = 986644
11 + 986633 = 986644
47 + 986597 = 986644
101 + 986543 = 986644
137 + 986507 = 986644
167 + 986477 = 986644
173 + 986471 = 986644
227 + 986417 = 986644

Showing the first eight; more decompositions exist.
