Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002778, here are decompositions:

5 + 1002773 = 1002778
11 + 1002767 = 1002778
59 + 1002719 = 1002778
131 + 1002647 = 1002778
251 + 1002527 = 1002778
311 + 1002467 = 1002778
401 + 1002377 = 1002778
419 + 1002359 = 1002778

Showing the first eight; more decompositions exist.
