Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002542, here are decompositions:

19 + 1002523 = 1002542
31 + 1002511 = 1002542
61 + 1002481 = 1002542
109 + 1002433 = 1002542
139 + 1002403 = 1002542
181 + 1002361 = 1002542
193 + 1002349 = 1002542
199 + 1002343 = 1002542

Showing the first eight; more decompositions exist.
