Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002644, here are decompositions:

61 + 1002583 = 1002644
67 + 1002577 = 1002644
127 + 1002517 = 1002644
151 + 1002493 = 1002644
157 + 1002487 = 1002644
163 + 1002481 = 1002644
193 + 1002451 = 1002644
211 + 1002433 = 1002644

Showing the first eight; more decompositions exist.
