Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002742, here are decompositions:

3 + 1002739 = 1002742
23 + 1002719 = 1002742
29 + 1002713 = 1002742
89 + 1002653 = 1002742
173 + 1002569 = 1002742
239 + 1002503 = 1002742
383 + 1002359 = 1002742
401 + 1002341 = 1002742

Showing the first eight; more decompositions exist.
