Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005088, here are decompositions:

17 + 1005071 = 1005088
47 + 1005041 = 1005088
59 + 1005029 = 1005088
101 + 1004987 = 1005088
107 + 1004981 = 1005088
401 + 1004687 = 1005088
419 + 1004669 = 1005088
431 + 1004657 = 1005088

Showing the first eight; more decompositions exist.
