Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002790, here are decompositions:

3 + 1002787 = 1002790
17 + 1002773 = 1002790
23 + 1002767 = 1002790
71 + 1002719 = 1002790
137 + 1002653 = 1002790
167 + 1002623 = 1002790
263 + 1002527 = 1002790
431 + 1002359 = 1002790

Showing the first eight; more decompositions exist.
