Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002842, here are decompositions:

73 + 1002769 = 1002842
103 + 1002739 = 1002842
163 + 1002679 = 1002842
223 + 1002619 = 1002842
331 + 1002511 = 1002842
349 + 1002493 = 1002842
409 + 1002433 = 1002842
439 + 1002403 = 1002842

Showing the first eight; more decompositions exist.
