Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002680, here are decompositions:

61 + 1002619 = 1002680
97 + 1002583 = 1002680
103 + 1002577 = 1002680
127 + 1002553 = 1002680
157 + 1002523 = 1002680
163 + 1002517 = 1002680
193 + 1002487 = 1002680
199 + 1002481 = 1002680

Showing the first eight; more decompositions exist.
