Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005278, here are decompositions:

37 + 1005241 = 1005278
61 + 1005217 = 1005278
199 + 1005079 = 1005278
229 + 1005049 = 1005278
271 + 1005007 = 1005278
367 + 1004911 = 1005278
499 + 1004779 = 1005278
541 + 1004737 = 1005278

Showing the first eight; more decompositions exist.
