Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008778, here are decompositions:

5 + 1008773 = 1008778
59 + 1008719 = 1008778
167 + 1008611 = 1008778
191 + 1008587 = 1008778
311 + 1008467 = 1008778
359 + 1008419 = 1008778
431 + 1008347 = 1008778
461 + 1008317 = 1008778

Showing the first eight; more decompositions exist.
