Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002872, here are decompositions:

19 + 1002853 = 1002872
103 + 1002769 = 1002872
151 + 1002721 = 1002872
163 + 1002709 = 1002872
193 + 1002679 = 1002872
349 + 1002523 = 1002872
379 + 1002493 = 1002872
421 + 1002451 = 1002872

Showing the first eight; more decompositions exist.
