Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005778, here are decompositions:

17 + 1005761 = 1005778
101 + 1005677 = 1005778
131 + 1005647 = 1005778
197 + 1005581 = 1005778
227 + 1005551 = 1005778
251 + 1005527 = 1005778
311 + 1005467 = 1005778
419 + 1005359 = 1005778

Showing the first eight; more decompositions exist.
