Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002530, here are decompositions:

3 + 1002527 = 1002530
7 + 1002523 = 1002530
13 + 1002517 = 1002530
19 + 1002511 = 1002530
37 + 1002493 = 1002530
43 + 1002487 = 1002530
73 + 1002457 = 1002530
79 + 1002451 = 1002530

Showing the first eight; more decompositions exist.
